Abstract:
1. An image forming apparatus having a power button for shifting the image forming apparatus to either a power shutoff state where power supply is shut off or a power-saving state where power supply is limited, a first depression time period of the power button for the power-saving state being different from a second depression time period of the power button for the power shutoff state, the apparatus comprising: a first accepting unit constructed to accept a first instruction with the power button depressed; a determination unit constructed to determine whether a depression time period of the power button accepted by said first accepting unit is shorter than a threshold which is specified between the first depression time period and the second depression time period; a display control unit constructed to, in a case where said determination unit determines that the depression time period is shorter than the threshold, control a display unit to display a screen for notifying to a user a shift to the power-saving state; a second accepting unit constructed to accept a second instruction regarding whether to execute the shift to the power-saving state via the screen displayed by said display unit; and a power control unit constructed to shift the image forming apparatus to the power-saving state in a case where said second accepting unit accepts the second instruction to execute the shift the power-saving state, and to stop shifting the image forming apparatus to power-saving state in a case where said second accepting unit accepts the second instruction not to execute the shift to the power-saving state.
