Abstract:
1. A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, said process cartridge comprising: an electrophotographic photosensitive drum; a developing roller configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive drum with a developer while being in contact with said electrophotographic photosensitive drum; a drum unit configured and positioned to support said electrophotographic photosensitive drum, wherein said drum unit is positioned relative to the main assembly of the apparatus when said process cartridge is set in the main assembly of the apparatus; a developing unit supporting said developing roller and movable relative to said drum unit between a contact position in which said developing roller and said electrophotographic photosensitive drum are in contact to each other to develop the electrostatic latent image and a spaced position in which said developing roller and said electrophotographic photosensitive drum are spaced away from each other; a movable member which is movable to move said developing unit between the contact position and the spaced position; and a movable member driving force receiving portion, provided in said drum unit, configured and positioned to receive, from the main assembly of the apparatus, a movable member driving force for moving said movable member when said process cartridge is mounted in the main assembly of the apparatus.
