Abstract
An image forming apparatus having a normal mode and a standby mode includes an image forming unit to form an image, a switching unit which selectively allows power to be supplied to the image forming unit, a controller to control the switching unit based on a phase signal of the power, a power cut-off unit which cuts off the power to the image forming unit in the standby mode, and a phase detector which is connected to both ends of the power cut-off unit, detects a phase of the power via different phase detection routes according to whether being in the normal mode or in the standby mode, and outputs the phase signal of the power so that a power consumption of the image forming apparatus does not exceed a predetermined value in the standby mode.
