Image forming apparatus and control method for the same

An image forming apparatus comprising:

• an image carrying member to carry a toner image;
• a drive device to drive the image carrying member;
• a cleaning member to slide in contact with the image carrying member so as to remove toner remaining on the image carrying member after transferring the toner image onto a sheet from the image carrying member;
• a controller, so as to perform a reverse rotation to rotate and stop the image carrying member in a reverse direction of a forward direction at time of image formation and then perform a forward operation to rotate and stop the image carrying member in the forward direction, to control the drive device on the basis of a use amount of the image carrying member;
• and
• rotation number detecting means for detecting the number of rotations of the image carrying member in the forward direction,
• wherein the cleaning member includes a cleaning blade and a portion where the cleaning blade and the image carrying member slide in contact with each other is located above a middle point of the image carrying member, and the cleaning member includes a recovery blade opposite to the cleaning blade and a spiral auger provided between the cleaning blade and the recovery blade so as to convey toner scraped off from the image carrying member, and
• wherein the controller uses the number of rotations from the rotation number detecting means as a use amount of the image carrying member, thereby decides a rotation amount of the reverse operation and a rotation amount of the forward operation.
