Abstract
According to one embodiment, an image forming apparatus includes an image carrier, a cleaning member, a determination unit, and a control unit. The image carrier carries a developer image. The cleaning member removes a developer adhering to a surface of the image carrier by a frictional force when the image carrier is rotated in a first direction. The determination unit determines an image forming amount in a plurality of continuous image forming jobs. The control unit rotates the image carrier in the first direction during the image forming period and in a second direction opposite to the first direction at reverse rotation timing, and changes a condition for rotation in the second direction according to the determination result.
