Abstract:
1. An image forming device comprising: an image carrier; a cleaning member, made of an elastic material, operable to clean a surface of the image carrier by contacting with the surface; a drive unit operable to rotate the image carrier in a reverse direction while the cleaning member is contacting with the surface of the image carrier, before the image carrier is rotated in a forward direction for an image formation; and a control unit operable to control the rotation of the image carrier in the reverse direction, in accordance with information indicating a size of a frictional force generated between the cleaning member and the image carrier being rotated, wherein the information indicates an image formation mode in which a preceding image formation job was executed, as an image formation history, and the control unit prohibits the image carrier from rotating in the reverse direction when the indicated image formation mode is a first mode in which one image formation job performs one image formation, and causes the image carrier to rotate in the reverse direction when the indicated image formation mode is a second mode in which one image formation job performs a plurality of image formations continuously.
