Abstract
A temperature-controlled quick heat roller having an electrical resistance heater sheet provided on an inner surface of the cylinder. The electrical resistance heater is made of at least a high-temperature-coefficient resistance layer so that when the high-temperature-coefficient resistance layer is heated by an electric current, the cylinder is set to a prescribed fixing temperature. Also, the heat roller has a property in which heating electrical power drops as the temperature thereof rises.
