A cartridge includes a developing roller and a frame configured to support the developing roller. A lever is connected to the frame, with the lever being movable relative to the frame, and with a part of the lever protruding beyond the frame. The cartridge also includes a memory board. and an electrode portion connected to the memory board. When the cartridge is oriented with the lever and the electrode portion at a bottom portion of the cartridge, the protruding part of the lever protrudes downward from the frame and at least a part of an exposed part of the developing roller is positioned above the rotational axis.

An image forming apparatus includes an apparatus body including a main contact, and a main guide, and a cartridge including a memory contact, a moving unit moving into and out of the apparatus body in a first direction and including a frame to which the cartridge is attached, first and second protrusions protruding in a second direction orthogonal to the first direction from the end surface of the frame, an intermediate contact being in electrical contact with the memory contact, an unit contact being in electrical contact with the main contact, and a line conductor, the first protrusion being supported by the main guide of the apparatus body, the second protrusion being located above the first protrusion. At least part of the line conductor connecting the intermediate contact and the unit contact is located in a recess formed by the first protrusion, the second protrusion, and the end surface.

Image forming apparatus with detectable cartridge

A cartridge includes a developing roller and a frame configured to support the developing roller. A lever is connected to the frame, with the lever being movable relative to the frame, and with a part of the lever protruding beyond the frame. The cartridge also includes a spring deformable in response to a movement of the lever relative to the frame, with the spring being positioned such that it is capable of exerting a first force on the lever and a second force on the frame. A memory board is provided and an electrode portion is connected to the memory board. A part of the electrode portion and a part of the spring are positioned in a plane that is perpendicular to a rotational axis of the developing roller.

A cartridge that is mountable to an apparatus main assembly of an image forming apparatus, the cartridge includes a developing roller; a frame supporting the developing roller; a movable part movably supported by the frame and movable to a first position and to a second position relative to the frame; and an elastic part provided between the frame and the movable part to urge the movable part. The movable part includes a first force receiving part that receives force from the apparatus main assembly, in a direction of moving from the first position to the second position, and a second force receiving part that receives force from the apparatus main assembly, in a direction of moving from the second position to the first position. When the movable part receives force from the apparatus main assembly at the first force receiving part and is at the second position, the movable part receives urging force from the elastic part in a direction of moving the movable part from the second position to the first position.

A cartridge includes a developing roller rotatable about a rotational axis thereof, and a frame configured to support the developing roller. A lever is connected to the frame, with the lever being elastically deformable such that a first part of the lever is movable relative to a second part of the lever and relative to the frame, and the lever protruding from the frame. A coupling member is configured to transmit a rotational force to the developing roller, the coupling member being rotatable about a rotational axis thereof, and the coupling member being movable relative to the frame in a direction of its rotational axis. When the cartridge is oriented with the lever and the electrode portion at a bottom portion of the cartridge, the lever protrudes downward from the frame.

An image forming apparatus includes a developer container to and from which a replenishment container is attachable and detachable, the developer container including an accommodating portion, and a supporting portion, wherein the developer container includes a projection portion that is provided at one end portion thereof in the rotation axis direction of the developer bearing member and projects toward the supporting portion more than a center portion of the developer container in a crossing direction crossing the rotation axis direction, the projection portion communicates with the accommodating portion and includes, at a distal end portion thereof, an attachment portion configured such that the replenishment container is attachable thereto in a state of being exposed to the outside of the apparatus, and a replenishment port for replenishing the accommodating portion with developer from the replenishment container is defined in the attachment portion.
