An image processing device includes a power supply unit, an operation unit, and an image processing unit. The power supply unit supplies power in first power supply mode or second power supply mode. The operation unit receives power from the power supply unit in first or second power supply mode and accepts an input from a user. The image processing unit receives the power if the power supply unit is in first power supply mode. At least one of the operation unit and the image processing unit determines whether a predetermined condition is satisfied if the power supply unit is in first power supply mode. At least one of the operation unit and the image processing unit is configured to perform a shutoff process to shut off power supply to at least one of electronic components in the image processing device if the predetermined shutoff condition is satisfied.
