Abstract
An image forming apparatus includes a fixing device, a driver, and a relay. A control board controls supply of power to a heater based on an output of a temperature detector. A connector includes a first connection portion to be connected to the fixing device, and a second connection portion to be connected to the control board, and connects the fixing device and the control board to each other. A loopback path is configured such that a direct current (DC) voltage to be applied, via a first terminal of the second connection portion, to a second terminal of the first connection portion is applied to a fourth terminal of the second connection portion via a third terminal of the first connection portion. Further, the DC voltage to be applied to the fourth terminal via the loopback path is applied to the relay as a drive voltage for the relay.
