Abstract
A method of controlling a transfer voltage of an image forming apparatus includes sensing an external temperature of the image forming apparatus, sensing an internal temperature of the image forming apparatus, determining a transfer voltage to be applied to a transfer roller according to the sensed external and internal temperatures, and applying the determined transfer voltage to the transfer roller. The method enables the image forming apparatus to improve a printing quality.
