摘要

A cleaning device may include a polishing roller, an ejection member, and a conveying member. In some embodiments, the polishing roller may be configured to remove and collect a residual substance adhering to a surface of an image bearing member while rotating in contact with the image bearing member. In an embodiment, the ejection member may be configured to eject the substance collected by the polishing roller to the outside of the cleaning device. An embodiment may include a conveying member configured to follow the rotation of the polishing roller by being in contact with the polishing roller and to convey toner in the cleaning device on a surface of the polishing roller in an axial direction of the polishing roller. When an image is not formed, the polishing roller rotates in a direction opposite a rotating direction in which the polishing roller rotates when an image is formed.
