Abstract: There is provided an image forming apparatus capable of performing short-distance wireless communication with a mobile terminal even when the image forming apparatus is in a low power consumption state. The image forming apparatus operates either in a normal power supply state or in a low power consumption state. If an NFC communication is established with a mobile terminal, the image forming apparatus operating in the low power consumption state shifts to the normal power supply state. Even when the image forming apparatus has been in the low power consumption state, the image forming apparatus can acquire ID data of the mobile terminal via the NFC communication. After shifting to the normal power supply state, the image forming apparatus performs authentication processing with the ID data acquired via the NFC communication.

Abstract: Backup control means controls processing for backing up data in storage means. In a state in which the storage means is not being supplied with power from the main power supply, a backup power supply supplies power to the storage means in order that backup processing by the backup control means will be performed. A timer measures power-supply time, which is the length of time the backup power supply supplies a voltage equal to or greater than a rated voltage to the storage means in order that backup processing will be performed. Determination means determines whether the power-supply time counted by the timer is shorter than length of a reference backup time. Notification of result of backup processing is given by alert means in accordance with the result of the determination made by the determination means.
