ABSTRACT:
A heating apparatus includes a heating roller that is heated by heating units, a main power supply that supplies power from an external power supply to the main heating unit, and an auxiliary power supply that supplies power to the auxiliary heating unit. The auxiliary power supply further includes a mass capacitor of multiple capacitor cells, 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.
