Abstract
The disclosure describes a fixing device for electrophotographic copying machine of the type in which a support carrying thereon a powder image is passed between a pair of rotary members so as to thermally fix the powder image on the support. At least one of said rotary members is heated by a heat source and its surface temperature is controlled by temperature detecting means to maintain it at a predetermined set temperature which is variable in accordance with various conditions of the copying machine, but satisfying a particular temperature relation specified therefor.
