Abstract
A fixation temperature control device is to be applied to a copying machine or the like. A control section determines a heat roller control temperature in consideration of a detected press roller temperature. When the heat roller temperature is lower than a reference temperature, a correction value is added to a heat roller reference temperature to set the heat roller control temperature higher than usual. When a fixing unit is in a stand-by status and the press roller temperature is in a temperature range between 80.degree. C. and 90.degree. C., a heat roller and a press roller are preferably rotated at a speed lower than a usual rotational speed.
