Abstract

Official abstract text for this publication.

An image forming apparatus includes a functional unit, a first power supply circuit supplying electric power to the functional unit from a commercial power supply, a second power supply circuit including a self-generation power supply, and a third power supply circuit including a power storage unit storing electric power and a charging circuit charging the power storage unit upon receipt of supply of electric power from at least one of the commercial power supply and the self-generation power supply. In accordance with the amount of power supply from the self-generation power supply, higher priority is given to supply of electric power to the functional unit from at least one of the second and third power supply circuits than to supply of electric power from the first power supply circuit.
