Abstract

A power control device and an image forming apparatus including the same are disclosed. A power control device meets the need for low power consumption by minimizing standby power consumption in a plug-on state of an electronic apparatus, and meets the safety requirements by increasing a discharging rate of an X-cap or an E-cap in a plug-off state. The power control device includes a first capacitor charged by AC power during input of the AC power, a rectifier converting the AC power to DC power, a second capacitor disposed at an output of the rectifier, and a discharge circuit including at least one discharge resistor, and a first switch and a second switch configured to be alternately turned on/off in response to supply and interruption of the AC power, and discharging at least one of the first and second capacitors via the at least one discharge resistor, in response to turn-off of the first switch and turn-on of the second switch.
