摘要： A process cartridge 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 apparatus. The cartridge includes an electrophotographic photosensitive member, a developing roller for developing an electrostatic latent image formed on the member with a developer, a developer accommodating portion accommodating the developer and having a developer supply opening for permitting passage of the developer to supply the developer to the roller, a sealing member unsealably sealing the opening and a grip member, provided on the sealing member, for being gripped to unseal the opening when the sealing member is removed from the opening. The grip member is movable between a first position where the cartridge can move to a predetermined position in the main assembly to permit transportation of the cartridge when mounted to the main assembly, and a second position where the cartridge is prevented from moving to the predetermined position from the first position when the cartridge is dismounted from the predetermined position.

摘要： A developing cartridge is detachably mountable to a main assembly of an image forming apparatus by passing through a mounting guide provided in the main assembly. The developing cartridge includes a frame; a developer carrying member for carrying a developer for developing an electrostatic latent image; a portion to be guided for being guided by the mounting guide when the developing cartridge passes through the mounting guide; an accommodating portion for accommodating the developer; a seal member for unsealably sealing an opening for permitting supply of the developer from the accommodating portion to the developer carrying member; and a grip member, provided at a longitudinal end portion of the seal member, including a fixed portion dismountably fixed on the frame and a grip portion to be gripped when the seal member is removed. The grip portion is disposed in a state in which the grip portion is bent relative to the fixed portion in a direction crossing a mounting direction of the developing cartridge. The grip portion prevents mounting of the developing cartridge by contacting a part of the image forming apparatus when the developing cartridge is mounted in the main assembly of the image forming apparatus.

摘要： An image forming apparatus includes a developing cartridge and rotatable member having a cartridge mounting portion with an engaging portion engageable with a portion of the cartridge. The cartridge includes a developing roller for developing a latent image formed on an image bearing member. The rotatable member is rotatable for moving the mounting portion between a mounting and demounting position for mounting and demounting the cartridge and another position. The engaging portion is movable between a regulating position, in which disengagement of the cartridge from the mounting portion is suppressed, and a permitting position in which the disengagement of the cartridge from the mounting portion is permitted. When the mounting portion is at the another position, the engaging portion is regulated at the regulating position. When the mounting portion is at the mounting and demounting position, the engaging portion is movable from the regulating position to the permitting position.
