ABSTRACT:
A power supply control device for an image forming apparatus of the present invention includes a shutoff detector for monitoring the state of a power switch. In response to the output signal of the shutoff detector representative of the turn-off of the power switch, a shutoff processing section executes processing for avoiding accidental error detection and protecting a memory before the output voltage of a DC power supply drops to a preselected level.
