Abstract
A fixing device includes a heating belt made of a conductive material, a pair of belt stretching rollers on which the heating belt is wound, and a pressure roller pressed against the heating belt via a specified nipping portion. A magnetic field generating unit is arranged opposed to the back of the heating belt at a portion equivalent to the nipping portion of the heating belt via an air layer for generating eddy current on the surface of the heating belt, and a power source applies high-frequency current to the magnetic field generating unit.
