Patent ID: 8589710

Claim:
An image forming device, comprising: a first circuit; a second circuit, the second circuit being at least partially different from said first circuit; a first power supply control unit configured to perform power supply control of said first circuit; and a second power supply control unit configured to perform power supply control of said second circuit; said first circuit having an acquiring unit configured to acquire a state of the image forming device, said image forming device being capable of operating in a print mode in which said first and second circuits are activated in accordance with the power supply control by said first and second power supply control units, a first power saving mode in which said first power supply control unit performs no power supply control so that said first circuit is not activated, and in which said second power supply control unit performs no power supply control so that said second circuit is not activated, and a second power saving mode in which said second power supply control unit performs no power supply control so that said second circuit is not activated, and in which said first power supply control unit performs the power supply control so that said first circuit is activated to perform the acquisition by said acquiring unit, said image forming device further comprising: a first switching unit configured to switch an operation mode from said first power saving mode to said second power saving mode in the case where an instruction to perform secure print is received while the device is operating in said first power saving mode; and a second switching unit configured to switch the operation mode from said second power saving mode to said print mode in the case where the identity of a user is authenticated while the device is operating in said second power saving mode.
