Abstract
An image forming apparatus includes a non-volatile storage unit, a power circuit, a power switch for the power circuit, a determination unit, and a power control unit. The determination unit is configured to determine an address through a predetermined method before power is turned off or voltage decreases after activation. The power control unit is configured to execute power-off processing in a case where an operation instruction of the power switch is provided after power-on processing and execute writing of information to be saved with respect to an address of the non-volatile storage unit previously determined by the determination unit in a case where a decrease in voltage of the power circuit is detected after the power-on processing.
