    Carbon Co ,, Ltd manufactured by DIC Corporation Dipentamethylenethiurama tetrasulfite (trade name: Next, in a crosshead extruder, an apparatus that includes a metal core feeding mechanism and a conductive cylinder unloading mechanism was prepared.
    A transport rate of the core metal was 80 mm / sec.
    A grinder that has an internal diameter of 12.5 mm was mounted on the crosshead.
    The temperature of the extruder and the crosshead were adjusted to 80 ºC.
    A layer of a non-vulcanized rubber composition has been formed on the circumference of the core metal fed to the “cross”, the core metal being a stainless steel bar that has an outside diameter of 66 mm and a length of 258 mm.
    Then, the core metal that has the circumferential surface coated with the non-vulcanized rubber composition layer was placed in a hot air vulcanization oven at 170 ° C and heated for 60 minutes to crosslink the non-vulcanized rubber composition layer. .
    In this way, an elastic layer of rubber was formed.
    Subsequently, the ends of the elastic rubber layer were cut and removed so that the length of the rubber was 228 mm.
    Finally, the surface of the elastic rubber layer has been polished by a recovery grinding wheel and shaped into a crown shape that has a central diameter! 12 mm and an average diameter of 11.8 mm at both ends located 90 mm to the left and right of the central portion.
    In this way, a No 1 elastic cylinder was obtained.
    Preparation Example B2: production of elastic cylinder No. 2 An elastic cylinder No. 2 was produced in the same way as in elastic cylinder No. 1, except that a non-vulcanized rubber composition obtained by mixing —the raw materials shown in Table 6 below by a cylinder mixer was used.
    Table 6! Dipentamethylene tyrram tetrasulfide (trade name: sms of Preparation B3: production of elastic cylinder No. 3 A stainless steel bar that has a diameter of 6 mm and a length of 258 mm was arranged inside a cylindrical metal mold.
    A mixture of liquid silicon rubber that includes the materials shown in Table 7 below was injected and filled into the cylindrical metal mold cavity.
    Table 7 Liquid silicone rubber (trade name: SE6724 A / B manufactured 100 parts by mass [o Dor cumne aaa ormeemee | Carbon black (trade name: TOKABLACK% 7360SB manufactured 35 parts by mass [o o caca A SPSS) cylindrical metal mold was heated at a temperature of 120 ºC for 8 minutes and cooled to a temperature of 25 ºC.
    Then, the stainless steel bar that has a layer of silicone rubber formed on its circumferential surface was released from the mold.
    Subsequently, the silicone rubber layer was treated at a temperature of 200 ºC for 60 minutes to cure the silicone rubber layer.
    In this way, a No3 elastic cylinder was obtained, an elastic layer that has a thickness of 3.0 mm that is formed on the circumferential surface of the stainless steel bar.
    Example 1: production of loading cylinder No 1; The elastic cylinder No 1 was immersed once in the No 1 coating solution prepared above to form a coating film of the No 1 coating solution | on the surface of the elastic layer.
    The immersion coating time was 9 seconds and the immersion coating pull rate was adjusted so that an initial rate was 20 mm / sec and the final rate was 2 mm / sec.
    The rate was linearly changed between 20 mm / sec and 2 mm / sec.
    Subsequently, the elastic cylinder 1 which has the coating film formed on its surface was left as it was in an environment at a temperature of 25 ºC for 30 minutes. Then, the elastic cylinder 1 was placed for 1 hour in a hot air circulation dryer set at a temperature of 90 “C. In addition, the elastic cylinder 1 was placed for 1 hour in the hot air circulation dryer set at a temperature of 160 “ºC to react to the coating film. In this way, a surface layer like the electrically conductive layer was formed on the elastic layer. In this way, the loading cylinder No 1 was obtained. The loading cylinder No 1 was subjected to evaluations as follows. Evaluation 1; volume resistivity measurement The current value of the loading cylinder has been measured and the volume resistivity of the loading cylinder No 1 has been calculated using the measurement result. Figures 2A and 2B are explanatory views that illustrate a method for measuring the current value of the loading cylinder. As shown in Figures 2A and 2B, at the same charge as in the charging cylinder when the electrophotographic imaging device is used, the charging cylinder comes into contact with a metal cylinder 22 that has the same curvature as that of the photosensitive member on the electrophotographic apparatus. In this state, the current was fluid and the current value at that time was measured. Figure 2A illustrates bearings 23a and 23b each attached to a weight and a loading cylinder 21 to be tested. Then, the stress is applied vertically and downwards to both ends of the electrically conductive support 11 for the loading cylinder 21. Vertically below the loading cylinder, a metal cylinder 22 is arranged so that the geometric axis of rotation of the cylinder of metal 22 is parallel to that of the loading cylinder 21. As shown in Figure 2B, the loading cylinder is pressed into the bearings 23a and 23b by a drive device, not shown, while the metal cylinder 22 is rotated. The DC voltage of -200 V is applied by a power supply 24 while the metal cylinder 22 is rotated at the same rotational speed as the photosensitive member when the electrophotographic apparatus is used and the charging cylinder 21 is rotated in a way that follows the turning of the metal cylinder
    22. After 2 seconds since the voltage is applied, the average time of the fluid current of the metal cylinder 22 was measured by an ammeter À and the average time of the results obtained by the measurement is 5 seconds was calculated. In this evaluation, two No 1 load cylinders to be tested were prepared. One of the No. 1 loading cylinders was placed at a temperature of 23 ºC / humidity of 55% RH (N / Environment) for 48 hours to acclimatize the No. 1 loading cylinder to the ambient N / N. Subsequently, under the same environment, an SN force was applied to each of both ends of the loading cylinder No 1 to bring the loading cylinder No 1 into contact with the metal cylinder having a diameter of 30 mm.
    The current value was measured while the metal cylinder was rotated at a circumferential speed of 150 mm / s and the electrical resistance value was determined.
    The other loading cylinder No 1 was placed in an environment at a temperature of 15 º C / humidity of 10% R.H. (Environment L / L) for 48 hours to acclimate the loading cylinder to the environment L / L.
    Subsequently, under the same environment, an SN force was applied to each of both ends of the loading cylinder No 1 to bring the loading cylinder No 1 into contact with the metal cylinder having a diameter of 30 mm.
    The current value was measured while the metal cylinder was rotated at a circumferential speed of 150 mm / s and the electrical resistance value was determined.
    The electrical resistivity of the loading cylinder No 1 under the L / L environment was divided by the electrical resistivity of the loading cylinder No 1 under the N / N environment and converted into the logarithm.
    The logarithm was defined as an environmental fluctuation digit.
    Thus, the dependence of the electrical resistivity of the charging cylinder No 1. environmental flotation can be evaluated Evaluation 2: spill assessment: The loading cylinder No. 1 was placed on a sheet of polyethylene terephthalate (PET) and a load of 500 g was applied to each of both ends of the emxo of the loading cylinder No 1 to make the surface of the loading cylinder No 1 contact the PET sheet.
    This state was maintained under an environment of a temperature of 40 * C / humidity of 95% RH. for a week.
    Subsequently, the loading cylinder No 1 was removed from the PET sheet and the surface of the PET sheet in contact by the loading cylinder No 1 was observed with an optical microscope (10 times magnification). It was verified whether objects spilled from the elastic layer of the loading cylinder No. 1 through the surface layer of the same and adhered to the surface of the PET sheet and evaluation were made, according to the criteria shown in Table 8 below.
    Table 8 of PET in contact by the loading cylinder. "Cloudiness" caused by slight adhesion of mixed objects is loading.
    PET in contact by the loading cylinder.
    Assessment 3: assessment of loading capacity An electrophotographic laser printer (trade name: Laserjet 4700dn) has been modified so that an emission rate of 200 mm / sec. Loading cylinder No 1 was mounted on the modified laser printer as the loading cylinder. The laser printer has an image resolution of 600 dpi.
    The laser printer was operated intermittently to form an image and 40001 sheets of an electrophotographic image were emitted. The intermittent operation to form an image means that after two sheets of an image are emitted, the rotation of the electrophotographic photosensitive member drum is stopped for approximately 3 seconds and the operation to form an image is performed again. The image emitted at that time was a character image that has a print density of 1% from the first sheet to the 40,000th sheet and a halftone image for the last sheet. Here, the halftone image was an image in which the horizontal lines were drawn a width of 1 point in the direction perpendicular to the rotational direction of the electrophotographic photosensitive member and an interval of 2 points. The 40,001th sheet of the halftone image was visually observed and evaluation was performed, according to the criteria - shown in Table 9 below.
    Table 9 seen in the halftone image.
    LR | eregemento were fixed and in the part of the loading mentom image were found in the halftone image part. seen in the halftone image part. were found in the halftone image.
    Evaluation 4: evaluation using defects similar to dots in the image The loading cylinder No. 1 was mounted on an electrophotographic laser printer (trade name: Laserjet 4515n, manufactured by Hewlett-Packard Company) as the loading cylinder. The laser printer has a recording medium emission speed of 370 mm / sec and an image resolution of 1200 dpi. The laser printer was operated intermittently to form an image and
    40,000 sheets of an electrophotographic image were issued. The intermittent operation to form an image means that after two sheets of an image are emitted, the electrophotographic photosensitive member gyro-drum is stopped for approximately 3 seconds and the operation to form an image is performed again. Í The image emitted at that time was a line image in H. A Line image | in H it was an image in which the horizontal lines were drawn a width of 2 points in the direction perpendicular to the rotational direction of the photosensitive member - electrophotographic and an interval of 176 points.
    Subsequently, a halftone image was emitted at an AC voltage to be applied of -600 V and a frequency of 2931 Hz, while the AC voltage to be applied was increased from Vpp = 1,200 V.
    Then, the tension at which the dot-like defects in the image disappeared was measured.
    According to this assessment, as the dot-like defects in an image disappear at a lower voltage, the electrical resistance value is more uniform in the charging cylinder.
    Evaluation 5: the molar ratio of the carrier molecule, according to the present invention, to all carrier molecules in the electrically conductive layer The surface layer of the loading cylinder No. 1 was scraped and dissolved in a dilute aqueous solution of hydrochloric acid to extract the carrier molecules in the ion-conducting resin.
    The aqueous solution after extraction was dried to recover an extracted product.
    Then, mass spectrometry by a flight time mass spectrometer (TOF-MS) and an ICP light emission analysis was performed to detect the amount of all carrier molecules that exist in the surface layer and the - amount of the molecule carrier in accordance with the present invention.
    In this way, the molar ratio of carrier molecule according to the present invention to all carrier molecules in the electrically conductive layer was determined.
    Examples 2 to 42 Loading rollers Nos 2 to 42 were produced in the same way as in the loading cylinder No 1 except that the coating solutions that have a number shown in Table 10 were used for the formation of the electrically conductive layer as the surface layer.
    These loading cylinders were evaluated in the same way as in the loading cylinder No 1.
