Abstract
A fixing apparatus includes a fixing belt, a steering roller, a pressure rotation member, and a contact-separation mechanism. The contact-separation mechanism moves the pressure rotation member to a position where the pressure rotation member is in a contact state with the fixing belt and a position where the pressure rotation member is in a separated state from the fixing belt. Swing of the steering roller is controlled so that the fixing belt moves to a predetermined position in a fixing belt width direction. A distance between a center position of the fixing belt in tilting the steering roller for a first time after the center position is separated from a center position of a range of movement of the fixing belt and the center position of the range of movement of the fixing belt in the width direction is smaller in the separated state than in the contact state.
