IMAGE FORMING APPARATUS AND TRANSFER POWER CONTROL METHOD THEREOF

摘要

PURPOSE: An image forming apparatus and an image transfer power controlling method thereof are provided to apply a transfer power to a transfer unit for setting up a target voltage in a constant current method. CONSTITUTION: A transfer power control unit(150) applies an initial transfer current to a transfer unit(120) in a predetermined section. The transfer power control unit sets up a measured output voltage of a power unit(140) as a target voltage. The transfer power control unit applies the set target voltage to the transfer unit.
