Abstract:
In an embodiment of the invention, it is detected whether an auxiliary power source device is mounted in an apparatus main body or not. When the auxiliary power source device is mounted in the image forming apparatus, after a specified time has passed in a printable state, power supply to a first heat roller to heat a heat roller is shifted to a sleep mode. When the auxiliary power source device is not mounted in the image forming apparatus, after a specified time has passed in the printable state, a shift is made to a preheat mode in which the heat roller is kept at a preheat temperature, and a specified time has further passed, a shift is made to a sleep mode.
