Abstract
A disclosed image forming apparatus includes a fixing unit configured to fix an unfixed image on a recording medium by bringing a first roller and a second roller in pressure-contact with each other; a contacting region detecting unit configured to detect a contacting region in which the first roller and the second roller are contacting each other, according to rotation of the first roller; a storing unit configured to store a contacting time in the contacting region detected by the contacting region detecting unit; and a rotation control unit configured to control the rotation of the first roller in such a manner as to change the contacting region in which the first roller and the second roller contact each other, based on the contacting time stored by the storing unit.
