A cartridge that can be inserted in an apparatus main body of an image forming apparatus by moving along an axial direction of an image bearing member includes the image bearing member, a frame configured to support the image bearing member, a storage member configured to store therein information on the cartridge, and include an electrical contact, and a first pressed section and a second pressed portion configured to be pressed by the apparatus main body. The electrical contact is disposed between the first pressed section and the second pressed section, and is configured to be in contact with the main body contact on a lower side in a state where the cartridge is attached to the apparatus main body.

Cartridge, process cartridge, and image forming apparatus

A second unit includes a restricted portion that comes into contact with a restricting portion provided to a body of an apparatus, the restricted portion coming into contact with the restricting portion, in order to restrict the movement of a developer carrier in a direction to make contact with an image carrier, when a developing cartridge has not reached a predetermined attachment position, and not coming into contact with the restricting portion when the developing cartridge is in the predetermined attachment position.

Developing cartridge including a member configured to be pressed by a member of an image forming apparatus

Disclosed is a developing apparatus including: a developer bearing member that bears a developer; a developing frame body that rotatably supports the developer bearing member; a one-end side end member that supports one-end side in an axis direction of the developer bearing member of the developing frame body; and another-end side end member that supports the other-end side in the axis direction of the developer bearing member of the developing frame body. Each of the one-end side end member and the other-end side end member is independently movable with respect to the developing frame body.

A developing cartridge includes a developing frame body rotatably supporting a developing roller. A first end member is attached to the first end of the developing frame and a second end member is attached to the second end of the developing frame body. The first end member and the second end member are rotatable independently of each other and relative to the developing frame body about a rotational axis common to the first end member and the second end member, and with rotation of the developing frame body relative to the first end member and the second end member, the developing roller moves from a first position to a second position in a direction that crosses a position of an axis of the developing roller when the developing roller is in the first position.

A developing cartridge includes a frame rotatably supporting a developing roller. The developing cartridge also includes a first supporting member attached to a first end of the frame, with the first supporting member being movable relative to the frame. The developing cartridge further includes a second supporting member attached to a second end of the frame, with the second supporting member being movable relative to the frame and the first supporting member.

Developing cartridge having a frame and supporting members that are movable relative to the frame

A method for disassembling a developing device. The developing device includes a frame configured to store a developer, a developer bearing member, a regulation member configured to regulate the developer borne by the developer bearing member, and a fixing member configured to fix the regulation member to the frame. The fixing member has a holding portion configured to hold the regulation member. The developing device includes a cover portion attached to the regulation member and configured to cover at least a part of the holding portion. The disassembling method includes cover removing for removing at least a part of the cover portion to reduce the size of a region of the holding portion covered by the cover portion.

Method for disassembling developing device and method for recycling developing device

Developing cartridge and image forming apparatus

A remanufacturing method of a developing device is provided. The developing device includes a frame configured to store developer, a developer carrying member configured to carry the developer, a regulating member including a regulating portion configured to regulate the developer carried on the developer carrying member, and a storage member configured to store the developer, the storage member being mounted on the regulating member. A storage portion configured to store the developer and a first opening communicating with the storage portion are formed between the storage member and the regulating member, the first opening is opposed to an exposed portion of the developer carrying member, and the exposed portion is exposed to an outside of the frame. The remanufacturing method includes forming a communicating hole communicating with the storage portion, and removing the developer from the storage portion.
