Abstract

PURPOSE:To perform excellent fixation by controlling the temperature of a heat insulating roller by a shielding member provided between a radiation heat source and the heat insulating roller. CONSTITUTION:Around radiation heat source 1, shielding member 9 with notch window 10 is provided and coupled with electromagnetic plunger 12 via arm 11. When plunger 12 is not in operation, window 10 faces to roll 3 and when in operation, it faces down. Switches 13 14 conducting on detecting sheet 2 and switch 17 turning on when the surface of roller 3 is at its melting-point temperature or higher are connected to power source 18 in parallel. In this constitution, switch 17 is normally turned off to heat roller 3 via window 10 and turned on at above the melting temperature to make the window face down, so that the surface temperature of roller 3 will be held below the melting temperature at above the softening temperature of a dust figure. For fixation, window 10 faces down to dissolve and bind the dust figure to sheet 2 tightly.
