  • Patent number: 6617551
    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.

  • Publication number: 20010050019
    Abstract: A heater, particularly useful for an imaging device, comprises a substrate primarily made of aluminum nitride (AlN) having an electrical insulating property. A heat generating member, formed on one surface of the substrate, contains silver (Ag) and palladium (Pd) having a weight ratio (Ag/Pd) in the range of 40/60˜50/50. Conductive electrodes are connected to respective ends of the heat-generating member.
