    FIELD OF THE INVENTION
    The invention relates to an image forming device based on electrostatic printing technology, in particular to one of the processing cartridges applied thereto. BACKGROUND OF THE INVENTION
    The invention relates to a processing cartridge which is removable disposed on an image forming device based on electrostatic printing technology, wherein the image forming device 10 may be any of a laser image forming device. , an LED image forming device, a copying machine or a facsimile apparatus.
    The working process of the image forming device based on electrostatic printing technology is as follows: firstly, predetermined charges are uniformly charged on the surface of a photosensitive member by a charge component, secondly, an image electrostatic latent is formed on the surface of the photosensitive member, with predetermined charges, is subjected to exposure treatment, thirdly, a developer is transported to the photosensitive member by developing components, so that the electrostatic latent image on the photosensitive limb surface can be developed; fourthly, the developer on the latent image is transferred to an image recording medium, such as paper, after the transfer, and finally the developer, which is not completely transferred onto the surface of the photosensitive member, is cleaned by a cleaning component, so that the photosensitive member is allowed to enter the next recharge, ie the next cycle.
    A processing cartridge is used in the imager device. As a cartridge unit, the processing cartridge is integrated with one or more of the following components: a photosensitive member such as a photosensitive organic drum and a series of components that act on the photosensitive member such as, the loading component, the cleaning component and the developing components.
    A processing cartridge in the prior art comprises two main structures, in which a loading roller, a cleaning blade and a photosensitive member are arranged on a first main structure; a developer, a magnetic roller and an adjustment blade used to adjust the thickness of the developer on the magnetic roller are reserved in a second main frame; the charge roller is regarded as a charge component, the cleaning blade is regarded as a cleaning component, the magnetic roller, the adjusting blade, etc. are regarded as the developing components and the first main and second structure Main frame, which are provided with the above components are assembled together to form the processing cartridge as a whole. The processing cartridge is mounted or dismounted on an image forming device by an end user, where a professional maintainer is not required, therefore maintenance is convenient for end users.
    In general, a motive force receiving opening is disposed in the photosensitive member and engaged with a drive mechanism in the image forming device to drive the photosensitive member to perform the rotational movement. However, as the photosensitive member is required to be willingly removable in the imaging device along with the processing cartridge, the motive power receiving opening and drive mechanism are required to be disengaged when the processing cartridge is disassembled to from the image forming device so that the processing cartridge can be successfully dismounted from the image forming device; and the motive power receiving opening and driving mechanism are required to be built-in when the processing cartridge is mounted within the image forming device for printing, so that the photosensitive member can rotate successfully.
    Chinese patent application CN 20092019260.3 describes a processing cartridge with a flexible pressure device. The flexible pressure device is arranged on a photosensitive drum and allows a driving force receiver to stably receive a driving force so that the driving force receiver has a free space in the axial direction of rotation of the photosensitive drum. Therefore, not only does the motive force receiver have a certain free space in the axial direction of rotation of the photosensitive drum and it reclines to a driving end of an image forming device to carry out the assembly of a toner cartridge in the axial direction of the photosensitive drum, but also the coaxial transmission between the motive power receiver and the photosensitive drum is safer and the structure is simpler. Furthermore, as the motive power receiver is detachably disposed at one end of the photosensitive drum, the photosensitive drum is convenient for maintenance. While different motive power receivers are used for different imager devices, but the main body, ie the photosensitive drum is the same, users only need to replace the motive power receiver and don't need to replace the photosensitive drum, therefore, manufacturing cost and utilization cost are reduced. At the ; However, due to the flexible pressure device, the motive force receiver, i.e. the motive force receiving opening, is always in the pressurized state when it starts to get engaged and disengaged with an image forming device drive mechanism, 5 thus, the motive force receiver and the driving member for the image forming device cannot be kept straight when they begin to get engaged and disengaged as the internal space of the image forming device is limited, consequently, the force receiver The drive and drive element of the image forming device are inevitably subjected to friction damage when they encounter a bevel as they begin to become engaged and disengaged and then the gear between the motive force receiver and the drive member of the imaging device is affected.

As illustrated in Figure 2, a push rod (13) and a first spring (18) are arranged on one side of a housing of the processing cartridge (10), in which a motive force receiving opening (12) is arranged, the pressure rod (13) and the first spring (18) are combined into a control mechanism; the pressure rod (13) is disposed within a guide groove (19) on the processing cartridge housing (10) and slides back and forth over the guide groove (19) in the X direction and the first spring (18 ) abuts a space / between an extended surface (13a) of the pressure rod (13) and an inclined surface (19a) of the guide groove (19) and provides an elastic restoring force to the pressure rod (13). When the processing cartridge is positioned over an image forming device, the extended surface (13a) of the push rod (13) tends to be too far from the slanted surface (19a) when the push rod (13) is under the first spring action (19); one end of the pressure rod (13) receives a force F applied from the outside to overcome the elastic force of the first spring (18) and the pressure rod (13) moves along the direction illustrated by a tip of arrow X and when force F is canceled, the pressure rod (13) performs restoring movement along the direction opposite to the direction illustrated by arrow X under the action of the elastic restoring force of the first spring (18).
    Figures 6 and 7 are schematic diagrams illustrating the interaction between the motive force receiving opening and the pressure rod, where figure 6 illustrates the state when the motive force receiving opening is retracted and figure 7 illustrates the state where the motive power receiving opening is extended. As illustrated in Figures 6 and 7, an extended surface (13a) and a retracted surface (13b) are disposed on the pressure rod (13) and are respectively arranged in a staggered fashion in the direction parallel to the length direction of the rod. pressure (13), ie, the X direction, and in the direction parallel to the axial direction of the motive force receiving opening, ie, the Y direction; height difference is formed between the extended surface (13a) and the retracted surface (13b) in the Y direction; the extended surface (13a) is upstream in the direction parallel to the X direction and the retracted surface (13b) is upstream in the direction parallel to the Y direction, and the extended surface (13a) and the retracted surface (13b) are subjected to bonding through a .' inclined surface (13c). As illustrated in Figure 6, when the push rod (13) is not pressed, the retracted surface (13b) supports a support base (12a) of the driving force receiving opening (12) in the axial direction of the driving force receiving opening. motive force (12) and the motive force receiving opening (12) is in the retracted state. As illustrated in figure 7, when the push rod (13) is pressed by force F, the push rod (13) moves in the X direction; in the process of moving, the support base (12a) of the motive force receiving opening (12) is transferred from the state of being supported by the retracted surface (13b) to the state of being supported by the extended surface (13a) through of the inclined surface (13c), and in the transient process, the motive force receiving opening (12) is extended in the Y direction and engaged with a drive mechanism (20) for the image forming device. When force F is canceled, the push rod 15 (13) is restored to the state shown in figure 6.
    In order to retract the motive power receiving opening (12) to ensure that the motive power receiving opening (12) is disengaged with the imaging device drive mechanism and the processing cartridge can be successfully disassembled from the image forming device, after force F is canceled, is illustrated as follows.
    As shown in Figures 8, 9, 10 and 11. Figure 8 is a cross-sectional view AA of the processing cartridge illustrated in Figure 1, when the push rod (13) is pressed and the receiving opening. motive force (12) is in the extended state; Figure 9 is a cross-sectional view A-A of the processing cartridge illustrated in Figure 1 when the push rod (13) is not pressed and the motive force receiving opening (12) is in the retracted state; Figure 10 is a stereogram of the driving force receiving J opening (12) for the processing cartridge; and Figure 11 is a stereogram of the motive power receiving opening (12) for the processing cartridge, after a pressure clamp (120) is mounted in the motive power receiving opening (12). As illustrated in Figures 8 and 9, a photosensitive member (11) is rotationally supported in a main housing of the processing cartridge, where a flange (11a) at one end of the photosensitive member (11) is supported by an axle pin ( 14) and a flange (11a) at the other end of the photosensitive member (11) is supported by a support (17). Under the support action of the axle pin (14) and the support (17), the photosensitive member (11) can only perform the rotational movement, around its axial line in the processing cartridge and cannot move along the axial direction of the photosensitive member (11).
    As illustrated in figures 8 and 9, a second spring (16) is disposed between the motive force receiving opening (12) and the flange (11a) for the photosensitive member (11), i.e. the second spring (16 ) is arranged between the flange (1 la) and the pressure fastener (120) of the power receiving opening (12). The second spring (16) provides an elastic restoring force to the driving force receiving opening (12), so that the driving force receiving opening (12) tends to move along the direction opposite to the Y direction. After the processing cartridge is mounted on the image forming device, the pressure rod (13) is pressed by force F; the motive force receiving opening (12) is supported by the extended surface (13a) and is in the extended state and the second spring (16) is compressed between the front end of the flange (11a) and the pressure fastener (120 ). When the processing cartridge is disassembled from the imager device, the force F is canceled, the pressure rod (13) performs the restoration movement along the direction • opposite to the direction illustrated by the arrow X under the action of the first spring (18), and the extended surface (13a) and support base (12a) are gradually disengaged; the motive force receiving opening (12) performs the retraction movement along the direction opposite to the direction illustrated by arrow Y under the action of the elastic force of the second spring (16) until the support base (12a) enters into contacting the retracted surface (13b) and being supported by the retracted surface (13b); and here, the motive force receiving opening (12) is in the retracted state and is disengaged with the drive mechanism (20) of the image forming device 10.
    The connection relationship between the motive force receiving opening (12) and the photosensitive member (11) and the motive force transmission process are illustrated as follows. As illustrated in figures 10, 11, 12 and 13, a transmission part (12b), a first guide position (12c) and a second guide position (12d) are arranged on the motive force receiving opening (12), the transmission part (12b) is arranged on a second guide position (12d); a tensioned groove (11b), a first guide groove (11c), a second guide groove (lld), steel plates (lie) and a plurality of 20 tensioned columns (llf) are arranged on the flange (11a) of the photosensitive member ( 11), the second guide groove (lld) is arranged in the side walls of the tensioned columns (llf); the transmission part (12b) is arranged in the tensioned groove (11b) and can be engaged with the tensioned columns (llf), and the transmission of the motive force is carried out between the motive force receiving opening (12) and the member photosensitive (11) through the transmission part (11b) and the tensioned columns (llf). When the motive force receiving opening (12) rotates, the transmission part (12b) joins the tension of the tensioned columns (llf), and the motive force receiving opening (12) transmits the motive force to the photosensitive member ( 11) through the transmission part (12b) to drive the photosensitive member (11) to carry out the rotational movement.
    As illustrated in figures 8, 10 and 12, the first guide position (12c) is arranged in the first guide groove (11c); the second guide position (12d) is arranged over the second guide groove (11d), and the first guide position (12c) and the second guide position (12d) can respectively slide in the axial direction of the photosensitive member (11) (or ie, the Y direction), in the first guide groove (11c) and the second guide groove (lld).
    The first guide position (12c), the second guide position (12d), the first guide groove (11c), the second guide groove (lld), the transmission part (12b), the tensioned columns (llf) and the second spring (16) are combined within the retractable mechanism.
    Figures 4 and 5 illustrate two conditions where blind spots occur when the steel plates (lie) are not disposed on the photosensitive member (11), when the driving force receiving opening and the drive mechanism (20) in the forming device are interlocked with each other. As illustrated in figures 4 and 5, when blind spots occur during coupling of the motive power receiving opening (12) and the drive mechanism (20), the motive power receiving opening (12) cannot be normally engaged with the drive mechanism (20), while the motive force receiving opening (12) cannot rotate in the photosensitive member (11) along the illustrated direction. Both conditions can result in the motive power receiving opening not being able to function normally.
    As illustrated in figure 3, when the motive force receiving opening (12) is arranged in the photosensitive member - (11), the transmission part (12b) is arranged between the steel plates (lib) between the tensioned columns (Ilf ). When the motive force receiving opening (12) is engaged with the drive mechanism (20) in the image forming device, the transmission part (12b) is always disposed between the steel plates (11b), so to ensure that blind spots cannot occur when the motive power receiving opening (12) is engaged with the drive mechanism (20).
    The embodiment can also be as follows: one end of the spring (16) contacts the motive power receiving opening (12), while the other end of the spring (16) contacts the housing of the processing cartridge (10), and the motive force receiving opening is disengaged with the actuation mechanism under the action of the spring force. SECOND ACHIEVEMENT:

The retractable mechanism adopted in the embodiment 10 comprises the axle pin (14), the support (17) and the flanges (11a) at both ends of the photosensitive member (11).
    As illustrated in Figures 13 and 14, a top plate (21) and a tension spring (22) are disposed at one end of the photosensitive member (11); the motive force receiving opening (12) 15 at the other end of the photosensitive member (11) is fixed on the flange (11a) of the photosensitive member (11); the top plate (21) is fixed to the processing cartridge housing 10, and one end of the tension spring (22) is fixed onto the top plate (21), while the other end of the tension spring (22) is fixed to the 20 photosensitive member (11). When the push rod (13) moves along the X direction and the motive power receiving opening (12) moves along the Y direction, the motive power receiving opening (12) is extended in the Y direction together with the photosensitive member (11) and engaged with the drive mechanism (20) in the imager device, and the tension spring (22) at the other end of the photosensitive member (11) is in the stretched state. When the push rod (13) is reset along the direction opposite the X direction, the motive power receiving opening (12) moves along the direction opposite the Y direction together with the photosensitive member (11) under the action of the tension spring (22) and is disengaged with the drive mechanism (20) in the image forming device. THIRD ACHIEVEMENT;
    The structure and process of operation of a retractable mechanism in the embodiment, which is the same as in the first and second embodiments, are not repeated here.
    In the invention, the retraction of the motive force receiving opening can not only be performed by a mechanical pressure mode, but can also be controlled by an electromechanical mode. The 10 implementation of a control mechanism is as follows:
    As illustrated in Figure 15, the embodiment adopts a single single coil solenoid valve (4d) to control engagement and disengagement of a motive power receiving opening (5d) on the driven side of a connector (14d) and a drive mechanism. drive (6d) of an image forming device. The motive power receiving opening (5d) is disposed at one end of a shaft (8d) of the connector (14d), and the other end of the shaft (8d) of the connector (14d) passes through a hollow cylinder of the solenoid valve (4d) and can move left or right with respect to the solenoid valve (4d), the solenoid valve (4d) is fixed in a housing of the processing cartridge (19d) and does not move when the shaft (8d) slides; one end of a metallic core A (17d) and the shaft (8d) are integrated as a whole, and the other end of the metallic core A (17d) can slide back and forth in a slot disposed at one end of a gear (16d) of a photosensitive member; the metal core A (17d) can adopt various structural shapes and can be disc-shaped, cross-shaped, spherical, etc., as the metal core A can slide into the groove arranged at the gear end of the photosensitive member, corresponding to the shape of the core A, the metallic core A (17d) of the core can transmit a motive force to the photosensitive member (16d) and rotates together with the photosensitive member (16d); a second elastic component (18d) is disposed between the solenoid valve (4d) and the core A (17d) and provides a restorative elastic force for the core A, where the restorative elastic force is used to restore the core A, after the solenoid valve is in the off state; and the solenoid valve (4d) is connected to an external power source through a connection (7d).

Figure 17 is a schematic diagram of a control circuit. When the circuit of the solenoid valve coil is turned on, the connected coil will generate a magnetic field and a magnetic force for the metallic core A (17d) due to electromagnetic induction, the magnetic force overcomes an elastic force of the second elastic component (18d) and attracts core A (17d) to be close to the solenoid valve; and the core A (17d) moves to the left along with the shaft (8d), so that the motive power receiving opening (5d) fixed to the driven side 20 of the connector is extended through the shaft (8d) and engages with the drive mechanism (6d) to the image forming device, thus the transmission of a rotating force is carried out. When the solenoid valve circuit is off, the coil is turned off, without generating the magnetic field, and without any magnetic attraction to the metallic A core (17d), in accordance with as illustrated in figure 16, the metallic A core (17d ) is driven to slide in the farthest direction from the solenoid valve under the action of the elastic force of the second elastic component (18d), and meanwhile, the motive force receiving opening (5d) is attracted by the shaft (8d) of the connector ( 14d) to slide on . ’ direction of the solenoid valve, so that the motive power receiving opening (5d) is disengaged with the drive mechanism (6d) for the image forming device. Therefore, the engagement and disengagement of the motive power receiving opening (5d) and the driving mechanism (6d) for the image forming device is well accomplished through the on-off control of the solenoid valve circuit.
    The power supply for operating the solenoid valve in the embodiment comes from the image forming device. As both the operating voltage and the operating current of the solenoid valve are low, a transformer to reduce the voltage and increase the current is needed to be added to the circuit. As illustrated in Figure 17, the direct current voltage (Vcc) is the power source for the image forming device; RI is a protective resistor; R2 is a solenoid valve coil impedance; LI and L2 are, respectively, primary and secondary coils of the transformer and the on/off state of the circuit is controlled by a switch S1.
    The solenoid valve of the embodiment can also be turned on via direct current. As illustrated in figure 18, an L3 inductor 20 for the removal of alternating current is required to be added to the circuit.
    The switch S1 in the circuit of the embodiment may be disposed within a primary coil circuit and may also be disposed within a secondary coil circuit, as long as the on/off control of the control circuit can be achieved. FOURTH ACHIEVEMENT:
    The third embodiment utilizes the single coil solenoid valve to control the extension and retraction of the motive power receiving opening. The invention can also use a double coil solenoid valve to achieve the same effect. The detailed description of another embodiment of the control mechanism is as follows:
    As illustrated in Figure 19, the embodiment adopts double coil solenoid valve 5 (15d) to control engagement and disengagement of a motive power receiving opening (5d) on the driven side of a connector (14d) and a drive mechanism (6d) on an image forming device. Structures that are the same as in the third embodiment are not described in detail here. The differences between this embodiment and the third embodiment are as follows: the solenoid valve of this embodiment is formed by two coils, i.e. a first coil (9d) and a second coil (10d); a magnet (lld) is disposed between the two coils and fixed over the solenoid valve and not contacting the two coils, and no elastic component is disposed between the solenoid valve (15d) and a metal core A of this embodiment.
    In this embodiment, the first coil (9d) and the second coil (10d) do not operate at the same time, and the condition that only one coil between the coils operates or both coils do not operate can be controlled by a circuit at any time, but the condition that both 20 coils operate at the same time cannot occur. Furthermore, the coils in this embodiment are subjected to instantaneous power, and the POH (hours on) is 3 seconds or less.
    As illustrated in Figure 21, the on/off state of the first coil (9d) and the second coil (10d) is controlled by a SPDT (single pole, double actuation) switch in the circuit. When the first coil (9d) is turned on, due to electromagnetic induction, the connected coil will generate a magnetic field and a magnetic force for a metallic core A (17d) so as to attract the core A (17d) to be close to the solenoid valve, thus the power receiving opening . drive (5d) attached to the oriented side of a connector is extended through a shaft (8d) and engaged with a drive mechanism (6d) for an image forming device. As the coils of this embodiment are subjected to instantaneous power, the attractive force from the first coil (9d) to the metallic core A (2) disappears after the coils are turned on. In order to ensure that the motive power receiving opening (5d) can continue to be closely engaged with the drive mechanism (6d) for the image forming device, the shaft (8d) of the connector is attracted by a magnet (lld ) in the solenoid valve 10 to be fixed in a position in which the motive force receiving opening (5d) is held to be engaged with the drive mechanism (6d) for the image forming device. When the second coil (10d) is turned on, due to electromagnetic induction, the connected coil will generate a magnetic field, but the directions of the 15 magnetic fields generated by the two coils are opposite each other like the first coil (9d) and the second coil (10d) share a positive electrode from the power supply. Therefore, the magnetic force of the magnetic field generated by the second coil (10d) to the metallic core A (17d) will drive the connector to perform the restoration movement. This means that, as illustrated in figure 20, the metal core A (17d) slides farther away from the solenoid valve, but a drive head slides closer to the solenoid valve, and the magnet (lld) attracts the shaft (8d) again to hold the shaft (8d) in a position in which the motive force receiving opening (5d) is disengaged with the drive mechanism (6d) for the image forming device. Therefore, the engagement and disengagement of the motive power receiving opening (5d) and the driving mechanism (6d) for the image forming device is well performed through the on/off control of the valve circuit - solenoid.
    The solenoid valve operating power supply in this embodiment comes from dry cells added to the processing cartridge. As illustrated in Figure 21, E is a dry battery pack 5; a SPDT (single pole, dual actuation) switch (S2) controls the first coil (9d) and the second coil (10d) to be turned on, respectively; and R3 and R4 are, respectively, impedances of the first coil (9d) and the second coil (10d).
    This realization can also be as follows: when the second coil (10d) is turned on, the core A (17d) is drawn closer to the direction of the solenoid valve, and when the first coil (9d) is turned on, a force repulsive is generated to direct the metallic A-core (17d) to slide farther away from the solenoid valve. That is to say, users only need to ensure that only one coil between the first coil (9d) and the second coil (10d) operates or both coils do not operate at any one time. FIFTH ACHIEVEMENT:
    The structures of this embodiment are basically the same as the first embodiment, so structures that are the same as the first embodiment (such as a retractable mechanism) are not described in detail here.
    A control mechanism adopted by this embodiment is as follows: Figure 22 is a sectional view of a processing cartridge of the embodiment. In this embodiment, a cable (15) passing through an axle pin (14) in a housing of the processing cartridge (10), is connected with a motive force receiving opening (12), and can slide in the photosensitive member ( 11) along the axial direction of the photosensitive member (11); the motive force receiving opening (12) is arranged on a flange (11a) for the photosensitive member (11) (the connecting means and the motive force transmission mode are the same as in the first embodiment); a pressure clamp (120a) is disposed over the motive force receiving opening 5 (12); one end of a second spring (16a) contacts
    the flange (11a), while the other end of the second spring (16a) contacts the pressure fasteners (120a) and the second spring (16a) is a pressure spring.
    As illustrated in figure 22, when the processing cartridge is disposed in an image forming device, a tension force F1 is applied to the cable (15) in the direction perpendicular to the axial direction of the photosensitive member. Due to the characteristic of the cable, the tension force F1 initiated by the cable (15) is transferred to a tension force F2 along the axial direction. Here, the tension force F2 causes the motive force receiving opening (12) to move to the left and the second spring (16a) to be in the compressed state. When the tension force F1 is canceled, the second spring (16a) is restored and causes the motive force receiving opening (12) to move to the right, and here the motive force receiving opening (12) is engaged with a drive mechanism in the image forming device. When the processing cartridge is disengaged with the image forming device, the cable (15) uses the tension force F1 again and the motive force receiving opening (12) is pushed to move to the left and be disengaged with the drive mechanism.
    The tensile force F1 in this embodiment can be transmitted from the outside, such as a handle of the processing cartridge. One end of the cable (15) is connected with the handle, while the other end of the cable (15) is connected with the motive power receiving opening (12). When the processing cartridge handle is extended,
    The cable (15) is stretched together with the handle and receives the tension force F1 from the handle and the motive force receiving opening is caused to move to the left. When the handle of the processing cartridge is not stretched, the handle (15) does not support the tension force F1 again 5 and the second spring (16a) urges the motive force receiving opening (12) to move to the right.
    The cable (15) of the embodiment can also be arranged on the casing of the processing cartridge (10) that supports the photosensitive member (11).
    In the invention, other elastic materials (such as elastic rubber and elastic steel plate) can be used to replace the spring, and the same technical effect can also be achieved. Elastic materials and the spring are known as elastic components. Therefore, the first and second spring in this embodiment are also known as the first and second elastic component, and the second spring in the third, fourth and fifth embodiment, may also be known as the second elastic component.
    A developer is accommodated in the processing cartridge in the above embodiments and the processing cartridge is also provided with the developing components for carrying out the development of the photosensitive member, a cleaning component, a loading component and so on. No detailed description is given here. SIXTH ACHIEVEMENT:

    A retractable mechanism comprises the driving force transmission part Ala, the pressure clamp A4 and the second spring A3, and a control mechanism comprises the circular boss Alb, the guide sleeve A5, the center ring A6, the pressure rod A9 , the first AIO spring and the All flange.
    The motive force transmission process of the motive force transmission mechanism assembly in the embodiment is described in detail as follows. As illustrated in figures 24 to 29, the opening of the Al motive power receiving and the A2 drive mechanism are in the disengaged state during installation of the A12 toner cartridge and are still maintained for a certain distance when the A12 toner cartridge is installed in the your place. After Al2 toner cartridge is installed and when a machine cover is closed, the A9 pressure rod is pushed through the machine cover on the image forming device (the equivalent of a printer described in Chinese patent application CN 2010101313861) to direct the central ring A6 connected with pressure rod A9 rotate clockwise along the radial direction of the photosensitive member. As the rotational movement of the guide sleeve is avoided due to the connection of the Alie clamping blocks on the flange Al 1 and the limiting axial interface A5e of the guide sleeve, the guide sleeve A5 can be driven, by the center ring A6 through the axial thrust generated by the center ring bevel A6a and a guide sleeve bevel A5a, to be extended along the axial direction of the photosensitive member, thus the driving force receiving opening Al arranged in the guide sleeve A5 is pushed to be extended and engaged with the drive mechanism A2, consequently, the drive mechanism drives the motive power receiving opening Al to drive the photosensitive drum A8 to rotate along the axial direction of the photosensitive drum A8. Here, both the second spring A3 and the first spring AIO are in the compressed state, and the extended axial displacement of the driving force receiving opening Al in the state is between 3.8 and 4.8 millimeters compared to that in the before state. of the machine lid by the image forming device is closed. After the The printing process is completed and when the machine cover for the image forming device is opened, the pressure applied to the pressure rod A9 by the machine cover on the image forming device is canceled and the pressure rod A9 with the 5 recovery function is retracted under the action of a force acting from the first spring AIO, so as to drive the center ring A6 to rotate counterclockwise along the radial direction of the center ring A6, the axial thrust between the bevel of the center ring A6a and the guide sleeve bevel A5a is canceled and the second compressed spring A3 is restored, so as to drive the driving force receiving opening Al to be picked up and disengaged with the A2 drive mechanism and the printing process is completed.
    As illustrated in figures 30 and 31, in this embodiment, a bevel of the positioning groove A7a is disposed within the flange 15 of the photosensitive member A7. The motive force transmission part Ala of the motive force receiving opening Al is arranged in the middle of the bevel of the positioning groove A7a before the motive force receiving opening Al is extended in the axial direction of the photosensitive member and engaged with the mechanism of drive A2, so that motive power receiving opening 20 Al can be driven to be extended in the axial direction of the photosensitive member and engaged with drive mechanism A2 while aligning with drive mechanism A2 (alignment means that the opening driving force receiving opening Al rotates a little about the axial direction of the driving force receiving opening 25, thus the phenomenon of finding blind spots during coupling of the motive force receiving opening Al and the drive mechanism A2 is avoided. In this invention, the processing cartridge is the same as the toner cartridge.
