Abstract:
1. A process cartridge detachably mountable to a main body of an electrophotographic image forming apparatus for forming an image on a recording medium, said process cartridge comprising: a rotatable electrophotographic photosensitive member; a charging roller for contacting said electrophotographic photosensitive member to charge said electrophotographic photosensitive member; a separation member for separating said electrophotographic photosensitive member and said charging roller from each other, and movable between a separation position for separating said electrophotographic photosensitive member and said charging roller from each other: and a contact position for bringing said electrophotographic photosensitive member and said charging roller into contact with each other; a rotatable driving force receiving member for receiving a driving force produced by said electrophotographic photosensitive member being rotated; and a rotatable driving force transmission member for being engaged with said driving force receiving member to transmit the driving force from said driving force receiving member to said separation member, in order to move said separation member from the separation position to the contact position, wherein play is provided in an engagement portion between said driving force receiving member and said driving force transmission member so that said driving force receiving member and said driving force transmission member can be freely rotated relative to each other by a predetermined angle so as to prevent said driving force receiving member from rotating when said separation member is moved from the contact position to the separation position.
