| 1. A method for supplying power to at least two heat generating members included in a fixing device, comprising:
supplying a first power to a first heat generating member from a commercial power source;
executing soft on control as to the first heat generating member for a predetermined period such that the first power is in
a restricted state when a temperature of the fixing device starts increasing;
charging an auxiliary power source to store charge using the commercial power source;
supplying a second power from the auxiliary power source to a second heat generating member before the executing soft on control
is terminated;
heating the fixing device with the first and second heat generating members; and
fixing an image onto a recording medium using the fixing device after the temperature of the fixing device reaches a prescribed
level.
