Abstract

A device includes an operating portion, a switch and a controller. The device is operable in a first mode in which a predetermined operation is executed and in a second mode of which power consumption is reduced rather than in the first mode, and operates in a state connected to an image forming apparatus. The operating portion operates by an AC voltage supplied from an external power source. The switch supplies the AC voltage to the operating portion in a conductive state and cuts off supply of the AC voltage to the operating portion in a non-conductive state. The controller operates by a DC voltage generated from the AC voltage by a power source provided in the image forming apparatus. The controller controls to cause the switch to be in the non-conductive state so as to stop operation of the operating portion when the device shifts from the first mode to the second mode.
