ABSTRACT:
The fixing apparatus includes: a fixing member having base and conductive layers and fixing a toner onto a recording medium when the conductive layer is heated by electromagnetic induction; a magnetic field generating member generating an alternating-current magnetic field crossing the conductive layer; and a magnetic field inducing member arranged so as to face the magnetic field generating member across the fixing member, and inducing the magnetic field into itself or allowing the magnetic field to go through the member. The base layer and the magnetic field inducing member each contain a material having a magnetic permeability change onset temperature in a range from not less than a heating preset temperature of the fixing member to not more than a heatproof temperature of the fixing member. A thickness of the base layer is smaller than a skin depth of the layer at the heating preset temperature of the fixing member.
