ABSTRACT:
A step-down circuit lowers a voltage outputted from a commercial power supply. A step-down-output control and charge control circuit controls a step-down voltage and charges a capacitor bank based on a step-down voltage outputted. A constant-voltage generating circuit generates a constant voltage based on an output of the capacitor bank or an output of the step-down circuit. An image-forming-apparatus control circuit supplies the constant voltage to a load that performs an image forming operation.
