Summary:PROBLEM TO BE SOLVED: To simplify a mechanism of moving a heating member toward a fixing member that fixes an image to a recording material and a mechanism of moving a heating member toward a supply member that supplies heat to a heating object.SOLUTION: A fixing device 100 includes a pressure roll 104 and a fixing belt 102, and heats and presses a sheet P to fix a toner image thereto. A temperature-sensitive magnetic member 114 is disposed inside the fixing belt 102, is formed into a circular arc following the inner circumferential face of the fixing belt 102, and is disposed opposing to an exciting coil 110, interposing the fixing belt 102. A deformation member 260 which is deformed by receiving heat from the temperature-sensitive magnetic member 114 is disposed between the temperature-sensitive magnetic member 114 and an induction material 118.
