<p>A heating apparatus is disclosed by which a problem, in which the temperature of a fixing roller tends to sharply change when a mass capacitor is employed as an auxiliary power supply, is solved. <??>The heating apparatus includes a heating roller (11) that is heated by heating units (11a and 11b), a main power supply (14) that supplies power from an external power supply to the main heating unit (11a), and an auxiliary power supply (15) that supplies power to the auxiliary heating unit (11b). The auxiliary power supply (15) further includes a mass capacitor that consists of multiple capacitor cells (15a and 15b), which are charged by the external power supply. The connection mode of the capacitor cells is changed at least at the time of electric discharge. <IMAGE></p> |
