Abstract:
1. An image forming apparatus comprising: a sleep control unit which makes a shift to a sleep mode with a lower power consumption than in a normal operation mode, in which at least power supply to a fixing device is stopped; a super-sleep control unit which makes a shift to a super-sleep mode in which a power source of a processor is turned off; a signal acquisition unit which acquires a signal serving as a trigger to cancel the super-sleep mode; a restoration control unit which turns on the power source of the processor and cancels the super-sleep mode in accordance with the signal acquired by the signal acquisition unit, and thereby restores an operation state with higher power consumption than in the super-sleep mode; and a restoration timer which sends a cancelation signal to cancel the super-sleep mode to the signal acquisition unit at time that is registered in advance, wherein the super-sleep control unit registers, in the restoration timer, time that is decided on the basis of time or a time period until the scheduled execution time of reserved processing having the closest scheduled execution time, of reserved processing with a processing execution time designated in advance, as the time when the restoration timer sends the cancelation signal.
