Abstract:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising:an electrophotographic photosensitive member; developing means for developing an electrostatic latent image formed on said electrophotographic photosensitive member with a developer; a developer container for containing the developer, said developer container having an opening for supplying the developer to said developing means; a sealing member for sealing the opening of said developer container; a winding member for winding said sealing member, said winding member being rotatably supported by said developer container; driving means for applying a driving force to rotate said winding member; and driving control means for permitting and preventing transmission of a driving force to said winding member, wherein said driving control means receives the driving force from the main assembly when said process cartridge is mounted to the main assembly of the apparatus, and prevents transmission of the driving force to said winding member by displacement in interrelation with rotation of said winding member.
