Abstract:
1. A fixing device comprising: a first cylindrical rotating member having an inner peripheral surface and an outer peripheral surface; a second rotating member that contacts the first rotating member; a magnetic field generation unit that generates a magnetic field, the magnetic field generation unit being provided at a predetermined distance from the inner or outer peripheral surface of the first rotating member; a heat generation member that generates heat by a magnetic field, the heat generation member being provided so as to oppose the magnetic field generation unit across the first rotating member and to contact the first rotating member, and having a thickness larger than a skin depth and containing a magnetic metal material; and a non-magnetic metal member containing a non-magnetic metal material, the non-magnetic metal member being provided at the inside of the first rotating member so as to oppose the magnetic field generation unit across the first rotating member and the heat generation member without contacting the heat generation member.
