摘要： A cartridge detachably attachable to an apparatus body, the apparatus body including a positioning portion configured to position the cartridge with respect to the apparatus body and a movable member configured to rotate from a first position to a second position, the first position being a position where a part of the movable member is configured to prevent the cartridge from being moved toward the positioning portion, the second position being a position where the part of the movable member is configured not to prevent the cartridge from being moved toward the positioning portion, the cartridge comprising: a portion-to-be-positioned protruding in a first direction and configured to position the cartridge with respect to the apparatus body in a second direction orthogonal to the first direction by abutting on the positioning portion of the apparatus body; and a pressing portion configured to press the movable member to move the movable member from the first position to the second position while the cartridge is being moved in the second direction, so that the portion-to-be-positioned passes by the part of the movable member to abut on the positioning portion.

摘要： To further develop a drive transmission method from a main assembly of an apparatus toward a cartridge.
The cartridge is detachably mountable to a main assembly of an image forming apparatus including a drive output member configured to output a driving force, and a main assembly side pushing member configured to incline the drive output member by pushing the drive output member. The cartridge includes a photosensitive drum and a cartridge side pushing member. The cartridge side pushing member is configured such that an inclination angle of the drive output member is changed by pushing the main assembly side pushing member.-

摘要： A cartridge mountable to a printer, said printer including a coupling guide contactable to a coupling of the cartridge to guide the coupling member. A case of the cartridge is provided with a hole for exposing a free end portion of the coupling to an outside of the cartridge, and a retracted portion provided in downstream of the hole with respect to the mounting direction of the cartridge. When the cartridge is mounted to a main assembly of the printer, the coupling guide enters the retracted portion from which the coupling member has retracted.

摘要： A cartridge detachably attached to an apparatus body of an image forming apparatus includes: a restriction member (60) provided on a toner cartridge (T), the restriction member being movable between a restriction position, at which relative movement between the toner cartridge attached to the attachment portion of the process cartridge (P) and the process cartridge is restricted by an engagement of the restriction member and the process cartridge, and a non-restriction position, at which the relative movement is not restricted; and a driving transmission unit (210, 211) for transmitting a driving force from the apparatus body to the toner cartridge by engaging with the apparatus body. The restriction member moves from the restriction position to the non-restriction position when a driving force reception unit receives the driving force from the driving transmission unit.

摘要： A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus including a movable member movable from an outside of the main assembly of the apparatus to an inside thereof while carrying the process cartridge. The cartridge includes a drum, charging and developing rollers, rotatably connected first and second frames supporting different rollers, drum and developing roller driving force receiving portions, first and second portions-to-be-supported, on one and the other ends of the first frame, first and second portions-to-be-positioned, on one and the other ends of the first frame positioned to first and second main assembly side positioning portions during a lowering movement of the movable member toward a transfer belt, charging and developing bias contacts exposed at the other end, and a portion-to-be-urged, on the first frame upper surface for receiving an elastic force to position the process cartridge relative to the main assembly.
