Abstract:
1. A process cartridge which is detachably mountable to a main assembly of an electrophotographic image forming apparatus and which is transportable in a state of being mounted to the main assembly of the electrophotographic image forming apparatus, said process cartridge comprising: an electrophotographic photosensitive member; a developing roller configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive member with a developer; a developer accommodating portion accommodating the developer and having a developer supply opening configured and positioned to permit passage of the developer to supply the developer to said developing roller; a sealing member configured and positioned to unsealably seal said developer supply opening; and a grip member, provided on said sealing member, and configured and positioned to be gripped to unseal said developer supply opening when said sealing member is removed from said developer supply opening, wherein said grip member is movable between a first position where said process cartridge is permitted to move to a predetermined position in the main assembly of the apparatus to permit transportation of said process cartridge in the state of being mounted to the main assembly of the electrophotographic image forming apparatus, and a second position where said process cartridge is prevented from moving to the predetermined position, wherein said grip member moves from the first position to the second position by an elastic force when said process cartridge is removed from the predetermined position.
