APPARATUS FOR POWER SUPPLYING AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

PURPOSE: An apparatus for supplying power and an image forming apparatus including the same are provided to quickly discharge the voltage of a capacitor in a power-off state and to prevent the electric shock of a user. CONSTITUTION: A preset voltage corresponding to the supply power of a first capacitor(217) is charged. A power detector(220) detects a power-on or a power-off state. A first control part(229) produces a first discharge control signal to discharge the voltage of a first capacitor. A discharge part(230) discharges the voltage of the first capacitor in response to the first discharge control signal. A switching transforming part(240) performs a switching voltage transformation operation in response to the switching drive signal transferred for the first control part .
