Abstract
A fixing device comprising: an endless fixing belt having a multilayer structure including a non-magnetic conductive layer and a first magnetic conductive layer, the non-magnetic conductive layer having a thickness smaller than a skin depth of a material thereof, the first magnetic conductive layer having a thickness smaller than a skin depth of a material thereof and being located farther from an outside surface of the fixing belt than the non-magnetic conductive layer; and a supporting member disposed inside the endless fixing belt and including a second magnetic conductive layer having a thickness larger than a skin depth of a material thereof. The first magnetic conductive layer and the second magnetic conductive layer have a higher specific resistance than the non-magnetic conductive layer, and the first magnetic conductive layer has been manufactured by plastic forming or plating.
