Abstract
A power control apparatus includes a heating roller provided to fix a toner image of print data in an image forming apparatus, the heating roller having a heating resistor to receive roller power. A maximum level of a source power supplied from an external source is gradually increased up to a specific maximum supply level and the maximum source power to the heating resistor is supplied as the roller power while gradually increasing the maximum level of the source power up to a specific maximum supply level. A surface temperature of the heating roller is measured, and the source power of which maximum level is equal to the maximum supply level is supplied to the heating resistor as the roller power until the measured surface temperature reaches a specific fixing target temperature, and the toner image is fixed onto a fed printing medium.
