Claim:
A fixing device comprising: a magnetic-field-producing member that produces an alternating-current magnetic field; a fixing belt that is heated by electromagnetic induction caused by the alternating-current magnetic field and fixes toner on a recording material; and a pressure applying member that is pressed against an outer peripheral surface of the fixing belt and forms a press-fixing part therebetween through which the recording material having an unfixed image is transported, wherein the fixing belt includes a metal body in which at least three layers are stacked, the at least three layers including a base layer made of metal; a protective layer made of metal; and a conductive layer provided between the base layer and the protective layer and to be heated by electromagnetic induction, and wherein, in a section of the fixing belt taken in a thickness direction, a neutral axis of the metal body resides on a side of the protective layer with respect to a thickness center line of the metal body and in the protective layer.
