Abstract: The image forming apparatus includes a cartridge and an image forming apparatus main assembly. An image forming apparatus main assembly includes a drive output member for transmitting the driving force to the cartridge. The drive output member is movable between an advanced position and a retracted position. An image forming apparatus main assembly includes an inclination imparting portion for inclining the drive output member as the drive output member moves from the advanced position to the retracted position.

Abstract: A cartridge includes a photosensitive drum, the movable member movable relative to the photosensitive drum to control an inclination angle of a drive transmission member. The movable member is movable between a first position for reducing an inclination angle of the drive transmission member relative to the photosensitive drum and a second position retracted from the first position. By this, driving connection can be smoothly carried out.

Abstract: A method of manufacturing a frame unit from a first unit. The first unit includes a first image carrying member, a supporting member supporting the first image carrying member, and a frame to which the supporting member is adhered. The first image carrying member includes a first edge portion member, and the first edge portion member includes a first restricted portion. The supporting member includes a bearing engaging with the first edge portion member so that the first image carrying member is rotatable about a rotational axis. The frame includes a first restricting portion restricting movement of the first image carrying member. The method includes separating in which the first image carrying member is separated from the supporting member while in a state in which the supporting member is adhered to the frame.

Abstract: A cartridge mountable to and dismountable from a main assembly of an image forming apparatus includes a memory, a guide configured to guide a portion-to-be-guided provided in the main assembly and to guide a main assembly contact provided in the main assembly to a memory contact of the memory when the cartridge is mounted in the main assembly, and a grip portion. The guide is provided at a bottom of the cartridge when the cartridge is hung by gripping the grip portion and constitutes a part of a supporting portion configured to support the cartridge when the cartridge is placed on a horizontal placement surface. The guide has a chamfered surface formed by being chamfered. When the cartridge is supported at the supporting portion, the chamfered surface opposes the horizontal placement surface, and a surface of the memory contact is inclined with respect to the horizontal placement surface.

Abstract: A manufacturing method includes a dividing step for dividing a supporting member into a first divided portion including a fixed portion to a frame and a second divided portion including a second engaged portion, a divided-portion detaching step for detaching the second divided portion from the frame, and a separating step for detaching an engaging portion from a first engaged portion and separating a developing unit from the frame.

Abstract: A manufacturing method includes a removing step for removing at least a part of a contact portion of a cover portion from a supporting member, the cover portion being configured to come into contact with a projecting portion included in a frame when the supporting member is deformed to allow a second engaged portion to be detached from an engaging portion in a state in which a fixed portion of the supporting member is fixed to the frame, a deforming step for deforming the supporting member to allow the second engaged portion to be detached from the engaging portion in the state in which the fixed portion is fixed to the frame, and a separating step for detaching an engaging portion from a first engaged portion and separating a developing unit from the frame.
