ABSTRACT:
There is provided a fixing device6including a heating body22which has a heating heat generation section24subjected to induction heating upon application of alternating magnetic fields generated by a exciting coil27, a pressure roller23which has a pressing heat generation section25being higher in magnetic permeability than the heating heat generation section24and being subjected to induction heating by a part of magnetic flux in the alternating magnetic fields leaking from the heating heat generation section24, and a drive circuit for applying drive voltage to the exciting coil, wherein a rate of the alternating magnetic fields leaking from the heating heat generation section24is changed by frequencies of the drive voltage.
