Process cartridge and image forming apparatus |
摘要 |
A process cartridge detachably mountable to a main assembly of an image forming apparatus. The process cartridge includes a photosensitive member unit including an electrophotographic photosensitive member, and a developing unit including a developing roller for developing an electrostatic latent image formed on the photosensitive member, the developing unit being movable between a contact position in which the developing roller is contacted to the photosensitive member and a separated position in which the developing roller is separated from the photosensitive member. The process cartridge also includes a drive transmitting portion for transmitting a driving force for driving the developing roller at one longitudinal end side of the developing unit. The drive transmitting portion provides to the developing unit a force for moving the developing unit in a direction from the separated position toward the contact position by receiving the driving force.
