| titleOfInvention | Process cartridge and image forming apparatus |
| abstract | To provide a process cartridge and an image forming apparatus capable of obtaining a uniform contact width to an image holding member and uniform charging to an image holding member regardless of the charging member of any diameter. For example, a process cartridge having an electrophotographic photosensitive member 1, a charging roll 21A for charging the electrophotographic photosensitive member 1, and a pressing roll 21B disposed in contact with the outer peripheral surface of the charging roll 21A, and In the image forming apparatus, the pressing roll 21B is charged to the charging roll 21A so as to press the charging roll 21A so that a force pressing the charging roll 21A against the electrophotographic photosensitive member 1 works in the normal direction of the contact surface with the charging roll 21A. It is arranged in contact with. The pressing roll 21B satisfies the conditions: Ac <Ae and 5 ° <Ac−Ae ≦ 20 °, where Ac is the Asker C hardness at the center in the longitudinal direction and Ac is the Ascar C hardness at both ends in the longitudinal direction. Is. [Selection] Figure 2 |
