Abstract

A fixing roller 3 is provided with a regulating member 40 that moves in an axis direction in contact with a fixing belt 5 that meanders. A heating roller 6 that comes close to/departs from the fixing roller 3 is provided with an adjustable member 41 that causes the heating roller 6 to move in the direction orthogonal to the axis direction in linkage with movement of the regulating member 40. The adjustable member 41 does not move in the axis direction and moves freely in the direction orthogonal to the axis direction. The meandered fixing belt 5 is displaced to one side of the axis direction to collide with the regulating member 40. The regulating member 40 is pushed by the fixing belt 5 to move toward one side. The adjustable member 41 is pushed by the regulating member 40 to move in the direction orthogonal to the axis direction, and the heating roller 6 moves so as to depart from the fixing roller 3. A center distance of axes between the fixing roller 3 and the heating roller 6 on one side enlarges, and the fixing belt 5 moves toward the other side. Accordingly, it is possible to suppress the meandering without applying force directly to the fixing belt 5 that meanders.
