description A pair of pressure members are disposed at both ends of a pressure roller and rotatably support the pressure roller to press the pressure roller against a fixing roller including an elastic layer via a fixing belt. One of the pressure members that includes a fulcrum engaging section engaged with a rotation fulcrum at one end and is locked to a biasing member at a side opposite to the fulcrum engaging section is moved by a moving member in a direction intersecting a pressing direction of the pressure roller in a state where deformation of the elastic layer is regulated. Thus, a force acting on a fixing nip formed by the deformation of the elastic layer of the fixing roller is stabilized. As a result, the traveling performance of the fixing belt is stabilized, whereby the offset control can be performed with high accuracy.
