ABSTRACT:
Disclosed is a fixing device having a self-temperature control function, and reducing a heat capacity of a heat generation member for saving energy and achieving good warm-up property. The fixing device includes a fixed plate inside a closed rotation path of a belt, contacting an inner circumferential surface of the belt, substantially opposed to an excitation coil with the belt therebetween, keeping the belt on the rotation path. The fixed plate includes: a magnetic shunt alloy layer made of a magnetic shunt alloy; a conductive heat generation layer being disposed toward a main surface of the magnetic shunt alloy layer facing the belt, being made of a conductor other than the alloy, and being thinner than the alloy layer; and a low resistance conductive layer being disposed toward another main surface, having a lower electric resistance value than the heat generation layer, and being thicker than the heat generation layer.
