Abstract
Disclosed is a method for controlling the temperature of a heat roller and an image forming apparatus based on the same. The image forming apparatus of the present invention includes: a heat roller for heating a printing paper having a toner image formed thereon to completely fuse the toner image to the printing paper; a heat lamp for heating the heat roller; and a controller for controlling the driving of the heat lamp, whereby the heat roller is maintained at a designated target temperature level during a pre-printing period. As such, it becomes possible to prevent a problem with the fusing process caused by low temperature of the heat roller during the pre-printing period for subsequent printing.
