  • a non-volatile storage device;

    a setting unit configured to calculate, when the image forming apparatus transits from the normal state to the power save state, a data retention period of said non-volatile storage device, and to set the calculated data retention period in a part of the image forming apparatus that operates in the power save state; and

    a transition unit configured to cause, by the part of the image forming apparatus that operates in the power save state, the image forming apparatus to transit from the power save state to the normal state based on the data retention period set by said setting unit,wherein the setting unit and the transition unit are implemented by a processor executing at least one program recorded on a memory device.
