ABSTRACT:
A transfer unit transfers a toner image formed on an image carrier onto a recording medium. A fixing unit includes a fixing roller and a pressure roller for fixing the toner image onto the recording medium by applying heat and pressure to the recording medium. At least one driving unit drives the fixing roller and the pressure roller. When stopping the fixing roller, a control unit controls the driving unit to stop the fixing roller such that the fixing roller and the pressure roller make a contact with each other at a contact position different from a previous contact position.
