Patent ID: 7805093

Claim:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising: an electrophotographic photosensitive member; a developing roller contactable to said electrophotographic photosensitive member to develop an electrostatic latent image formed on said electrophotographic photosensitive member; a photosensitive member unit supporting said electrophotographic photosensitive member so that a part of said electrophotographic photosensitive member is exposed; a developing unit supporting said developing roller and movable relative to said photosensitive member unit between a contact position for contacting said developing roller and said electrophotographic photosensitive member with each other to develop the electrostatic latent image and a spaced position for spacing said developing roller and said electrophotographic photosensitive member from each other; a movable member configured and positioned to transmit a driving force from said electrophotographic image forming apparatus for moving said developing unit between the contact position and the spaced position; and an engageable member configured and positioned to be engageable with said movable member to regulate movement of said movable member with said developing unit positioned in said spaced position.
