ABSTRACT:
A method of controlling the surface temperature of a fixing roller of a heat roller type fixing device which is installed in an electrophotographic copier, facsimile apparatus for similar image forming apparatus. When a thermistor which is responsive to the surface temperatures of the fixing roller fails or it is positioned inaccurately relative the roller, the method prevents the surface temperature of the roller from being sensed erroneously and thereby eliminates unusual rises and falls of the surface temperature.
