。[Claims for Utility Model Registration] A fixing roller having an internal heater and a pressure roller that comes into pressure contact with the fixing roller, and by pinching and conveying the paper on which the toner image has been transferred between both rollers. In the temperature control device of the fixing device that performs image fixing, a temperature detector detects the environmental temperature at the start of fixing, and the temperature detected by the temperature detector is compared with a predetermined low temperature reference temperature, and the detected temperature is determined. A comparison means outputs a signal indicating whether the low temperature reference temperature has been reached, and a signal output from the comparison means when the detected temperature at the start of fusing has not reached the low temperature reference temperature, is used to determine the predetermined fixing set temperature. 1. A temperature control device for a fixing device, comprising: a fixing temperature changing unit that outputs a higher control temperature.
