Abstract
A heater having a substrate composed of a heat-resistant and electrically insulating material, a heater element formed on the surface of the substrate in a belt-shape in the longitudinal direction containing an alloy of Ag and Pd having a weight ratio Ag/Pd of 90/10 to 70/30, glass, and an inorganic oxide and/or an inorganic nitride of 0.1 to 20 wt % to the weight of the alloy of Ag and Pd, and a power supply terminal part formed in connection with the heater element. The heater is suited to use for a fixing device of an image forming apparatus.
