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.
