<P>PROBLEM TO BE SOLVED: To solve the problem that the temperature of a fixing roller tends to sharply change when a large-capacity capacitor is used as an auxiliary power supply. <P>SOLUTION: A heating device includes a heating part 11 whose temperature is raised by heat generation of heat-generating members 11a and 11b, a main power supply 14 supplying power to the heat generating member 11a with the use of a commercial power supply, and a large-capacity capacitor composed of a plurality of cells 15a and 15b used as the auxiliary power supply 15 charged by the commercial power supply and supplying power to the heat generating member 11b. The connection of the plurality of the cells 15a and 15b is structured to be variable at least during discharge. <P>COPYRIGHT: (C)2007,JPO&INPIT |
