Abstract
An image forming apparatus including: an image forming portion; a fixing portion; an electric storage portion configured to supply electric power to a load; a first power supply configured to supply electric power to the load; a second power supply configured to supply electric power to the fixing portion; and a controller configured to supply electric power from the electric storage portion to the load and supply a predetermined maximum allowable power from an AC power supply to the second power supply when an image formation request is input, wherein in a case where a remaining amount of the electric storage portion becomes lower than a predetermined value, the controller reduces electric power supplied from the second power supply to the fixing portion lower than the maximum allowable power, and thereafter switches an electric power supply to the load from the electric storage portion to the first power supply.
