A method for regulating a temperature of a fixing unit in an electrophotographic system contemplates the steps of preheating the fixing unit in response to application of electrical power to the fixing unit; heating a surface of a heating roller of the fixing unit to a heightened temperature that is greater than a printing temperature during an initial printing stage of a printing operation when a number of sheets that have been printed in the printing operation is less than or equal to a predetermined number, and heating the surface of the heating roller to the printing temperature when the number of sheets that have been printed in the printing operation is greater than the predetermined number; printing one of the sheets after the heating step; determining whether a last one of the sheets has been printed; returning to the heating step when the last one of the sheets has not been printed, and terminating the printing operation and activating a standby mode when the last one of the sheets has been printed. According to a preferred embodiment of the present invention, the temperature difference between the heightened temperature and the printing temperature is in a range from 3 DEG C. to 30 DEG C., and the predetermined number equals five.
