Abstract
In an image forming apparatus having a power button for shifting the apparatus to either a power shutoff state where power supply is shut off or a power-saving state where power supply is limited, the image forming apparatus is shifted to the power-saving state when the press continuing time of the power button is shorter than a threshold, and shifted to the power shutoff state when it is longer than the threshold. When the press continuing time is shorter than the threshold, information indicating that the shift will occur is displayed on a display unit before the image forming apparatus is shifted to the power-saving state.
