Abstract:
1. A fixing device for fixing a toner image on a recording sheet after fusing the toner image by using a fixing belt heated due to electromagnetic induction caused by an excitation coil, 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 endless 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, wherein 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 a process selected from the group consisting of plastic forming and plating.
