A temperature control method for use in a fusing device of image forming apparatus having a fusing roller and a heater heating the fusing roller, including: sensing a surface temperature T of the fusing roller at one of when the image forming apparatus is turned on, when the image forming apparatus begins a normal operation from a power saving operation, and when a cover of the image forming apparatus is closed after being opened; comparing the sensed surface temperature T of the fusing roller with a set temperature; driving the heater until the surface temperature T reaches a first target temperature Tt<SUB>1 </SUB>when the sensed surface temperature T is below the set temperature; and driving the heater until the surface temperature T reaches a second target temperature Tt<SUB>2 </SUB>when the sensed surface temperature T is over the set temperature.
