Process cartridge and electrophotographic image forming apparatus

摘要

A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes a drum frame for supporting a electrophotographic photosensitive drum and a developing member for developing an electrostatic latent image formation d on said electrophotographic photosensitive member; a developing frame supporting said developing member, wherein said developing frame is provided at a longitudinal end thereof with a projected portion which is projected in a longitudinal direction of said developing member and which is engaged with a guide member, wherein said projected portion is movable along the guide member toward said drum frame, and wherein said developing frame is swingablely connected with said drum frame at the other longitudinal end, wherein said developing member is supported on said developing frame for movement in a direction crossing with the longitudinal direction; an elastic member for urging said projected portion along said guide portion toward said drum frame. <IMAGE>
