Patent ID: 8548354

Claim:
A process cartridge including a photosensitive member unit having an electrophotographic photosensitive member and including a developing unit having a developing roller for contacting said electrophotographic photosensitive member and for developing an electrostatic latent image formed on the electrophotographic photosensitive member, said developing unit being movable relative to said photosensitive member unit to contact and space said developing roller relative to said electrophotographic photosensitive member, said process cartridge being usable with an electrophotographic image forming apparatus, wherein the electrophotographic image forming apparatus includes a main assembly, a supporting member movable between an inside position that is inside of the main assembly to effect a developing operation and an outer position that is outside the main assembly and in which said process cartridge is mountable and dismountable, and a contacting and spacing member provided movably on the supporting member and actable on said developing unit, the contacting and spacing member being movable between a first position for contacting said developing roller to said electrophotographic photosensitive member and a second position for spacing said developing roller from said electrophotographic photosensitive member, said process cartridge being detachably mountable to the supporting member, said process cartridge comprising: a force receiving portion, provided on said developing unit and projected in an axial direction of said developing roller, for receiving, from the contacting and spacing member taking the second position, a force for spacing said developing roller from said electrophotographic photosensitive member.
