Abstract:
1. An image forming apparatus configured to operate in a first power state and a second power state in which power consumption is smaller than power consumption in the first power state, the image forming apparatus comprising: a detection unit configured to detect an object present around the image forming apparatus; and a power-supply control unit configured to shift the state of the image forming apparatus from the second power state to the first power state, when the detection unit detects an object present around the image forming apparatus, wherein, in a case where an operation unit configured to receive a user operation is operated by a user after the power-supply control unit shifts the state of the image forming apparatus from the second power state to the first power state, the power-supply control unit shifts the state of the image forming apparatus from the first power state to the second power state after a lapse of a predetermined time, and in a case where the operation unit is not operated by the user after the power-supply control unit shifts the state of the image forming apparatus from the second power state to the first power state, the power-supply control unit shifts the state of the image forming apparatus from the first power state to the second power state before a lapse of the predetermined time.
