A method for controlling a fixing unit of an image forming apparatus is provided to increase the printing speed of the fixing unit by detecting a temperature variance of the fixing unit when non-paper is transferred and varying the rotating speed of the fixing unit based on the temperature variance of the fixing unit. A temperature of a fixing unit is measured right after proceeding printed paper is completely fixed(S10). The measured temperature is compared with a fixing reference temperature(S20). When the measured temperature is deviated from a range of the fixing reference temperature, a rotating speed of the fixing unit is changed in a moving section of non-paper(S40). When the measured temperature is higher than the fixing reference temperature, a heater of the fixing unit is turned off.
