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