Image processing apparatus, image recording apparatus, controlling method for these apparatuses, and power supply apparatus used therein

摘要

An apparatus having a power supply section capable of outputting plural power supply voltages is provided with a sleep mode (energy-saving mode) for inhibiting at least one of the outputs from the power supply section in a wait state. Furthermore, an image forming apparatus such a printer is provided with a cut-off function for inhibiting at least one of the outputs from the power supply section supplied to a heater of a fixing device if an abnormality is detected, so that by relating the operation of this cut-off function and the operation of inhibiting at least one output at the power supply section to each other, these operations may be more easily controlled and also the number of components required can be reached.
