Abstract: A cleaning unit includes a cleaning member, an accommodating portion, and a transport member. The cleaning member removes a developer from a surface of an image carrier. The accommodating portion accommodates the removed developer. The transport member transports the developer removed by the cleaning member to the accommodating portion. The transport member includes a shaft member and first and second transport bodies. The shaft member extends in a direction intersecting a transport direction of the developer. The first transport body is rotatably supported by the shaft member. The second transport body is rotatably supported by the first transport body at a position spaced from the shaft member. The second transport body extends toward the cleaning member. When the shaft member rotates, a trajectory of an end portion, at a cleaning member side, of the second transport body is an ellipse elongated along the transport direction on the cleaning member.

Abstract: A cleaning unit includes a cleaning member that removes a developer from a surface of an image holding member; an accommodating portion that accommodates the removed developer; and a transport member that transports the developer removed by the cleaning member to the accommodating portion, wherein the transport member includes a transport unit that extends in a direction intersecting with a developer transport direction, has a surface formed to be inclined in a direction approaching the cleaning member towards an upstream side, and transports the developer while contacting with the developer.

Abstract: An image forming apparatus includes an image forming unit, a developer replenishing device, a fixing device, a press-contact adjustment mechanism, first and second driving transmission mechanisms, and a driving switching mechanism. The image forming unit forms a developer image on a recording medium. The developer replenishing device and the fixing device are detachable. The developer replenishing device replenishes a developer. The fixing device includes first and second rotation members. The second rotation member faces the first rotation member. The fixing device fixes the developer image to the recording medium. The press-contact adjustment mechanism adjusts a press-contact state between the first and second rotation members. The first driving transmission mechanism transmits a driving force to the press-contact adjustment mechanism. The second driving transmission mechanism transmits a driving force to the developer replenishing device.

Abstract: A developer replenishment device includes a developer transport member, a joint member, and an elastic member. The developer transport member transports a developer to a developing device. The joint member is attached to an end portion of the developer transport member on a side of the developing device so as to be relatively displaceable with respect to the developer transport member to be joined to the developing device so as to be able to replenish the developing device with the developer. The elastic member is interposed between the developer transport member and the joint member, and includes a guide hole that guides the developer from the developer transport member to the joint member.
