An image forming apparatus includes a heat radiation unit to emit heat by an operating power supplied to the heat radiation unit, a switching unit (130) to supply the heat radiation unit with the operating power, a relay unit (140) to control the operating power to be supplied to the switching unit (130), a malfunction detector (160) to detect whether the operating power is being supplied to the heat radiation unit and to output a malfunction signal corresponding to the switching unit (130) or the relay unit (140) if the power is not supplied thereby denoting a malfunction, and a controller (180) to output an off-signal to at least one of the switching unit (130) and the relay unit (140) if the malfunction signal is received from the malfunction detector (160). |
