<P>PROBLEM TO BE SOLVED: To provide a heating device of simple structure and heightened power saving efficiency of which, a space for installation is reduced by reducing the volume of an auxiliary power source. <P>SOLUTION: A main heating element 22a generating heat by the power supplied from a main power source device 23, and an auxiliary heating element 22b generating heat by the power supplied from an auxiliary power source device 24 having a capacitor of large capacitance are arranged to a heating part 22, and a power of allowable maximum capacity of the main power source device 23 is supplied to the main heating element 22a by stopping to charge the capacitor of the auxiliary power source device 24 while the power is supplied from the main power source device 23 to the main heating element 22a. At the same time, by supplying power from the auxiliary power source device 24 to the auxiliary heating element 22b, a larger amount of power when compared with the supplied only from the main power source device, is supplied to the heating part 22. <P>COPYRIGHT: (C)2003,JPO |
