摘要： A process cartridge comprises a photosensitive drum and a developing roller. A coupling member is provided adjacent to one axial end of the developing roller. The coupling member includes a driven portion, and an intermediary portion configured and positioned to engage with the driven portion. The intermediary portion is also configured to be movable relative to the driven portion in a direction crossing the axis of the developing roller while maintaining engagement with the driven portion. The coupling member further includes a driving portion configured and positioned to receive a driving force for rotating the developing roller. The driving portion is also configured to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.

摘要： An image forming apparatus includes a stopper movable between a stopping position in which the stopper contacts with a downstream end portion of a cartridge, having a first contacting portion and a second contacting position, in a mounting direction, to stop the cartridge from being moved in the mounting direction and a non-stopping position in which the stopper is retracted from the stopping position so as not to stop the cartridge from being moved in the mounting direction. The stopper moves from the stopping position to the non-stopping position in conjunction with movement of a movable member from a first position to a second position.

摘要： A cartridge for an image forming apparatus including a movable member is provided with a first engaging portion and a second engaging portion movable between a first position and a second position. The cartridge includes a first engaged portion engageable with the first engaging portion, and a second engaged portion engageable with the second engaging portion. By the first engaged portion being engaged with the first engaging portion in the process of mounting, the movable member is moved from the first position to the second position to permit the second engaged to pass the second engaging portion in a mounting direction.

摘要： An apparatus body includes an elastic body-side terminal, which is a terminal for supplying electricity to a cartridge. The cartridge includes: a developing apparatus that develops as a developer image an electrostatic latent image formed on an image bearing member; a cartridge-side terminal for supplying electricity from the apparatus body; and a frame having an opening that exposes the cartridge-side terminal. In a process of attaching the cartridge to the apparatus body, the body-side terminal makes contact with the cartridge-side terminal by being inserted into the opening. The body-side terminal presses the cartridge-side terminal in a state in which the cartridge is attached to the apparatus body.
