Abstract
A fixing heater is provided that employs, as a heating element, a material having small heat capacity and excellent wear resistance. A metal or semi-metal compound that can act as an electrical conduction inhibiting material is mixed into a carbon-containing resin such as a furan resin, chlorinated vinyl chloride resin, etc., and a pattern of a heating element is formed on a substrate, by screen printing, and then is sintered at temperature of about 1000° C. to obtain a fixing heater including amorphous carbon and having NTC characteristics.
