Abstract
Apparatus for fixing a toner image on a support by pressing and heating it. To heat the toner image, the apparatus comprises first heating means for heating it with transmission or convection heat and second heating means for heating the same with radiation heat. A detecting means detects the temperature of the first heating means and in accordance with the detected information the second heating means is controlled so as to maintain the thermal condition for fixing in a constant and stable state with improved thermal efficiency.
