In the control method, power is supplied from the main power supply to the stop state where the main power supply is stopped, the start state where power is supplied to the plurality of devices from the main power supply, and some devices among the plurality of devices. The image forming apparatus selectively shifts to each state of the power saving state, which consumes less power than the start state, and further, to an image forming portion among an image forming portion forming an image on a recording material and a plurality of devices. A first control unit that controls devices other than included devices, and an image forming unit, and also executes start processing of the image forming unit when the image forming apparatus starts from a stopped state or a power saving state. In the control method of an image forming apparatus including: two control units, when the image forming apparatus is activated from a stopped state or a power saving state, predetermined communication is performed when the first control unit completes its activation. A step of outputting the command, a step of measuring an elapsed time from the time when the second control means starts the second control means, and an elapsed time measured by the second control means Starting the start processing of the image forming unit in response to receiving the communication command from the first control unit before reaching the predetermined time of 1; and the second control unit generates the first control unit from the first control unit And D. starting the start-up process of the image forming unit in response to the elapsed time reaching the first predetermined time without receiving the communication command .
