Fixing device

Abstract

Abstract PURPOSE: To enhance the fixing capacity by using plural thermal sources by combining them in accordance with the selection of a copy mode. CONSTITUTION: The first heat source consisting of fixing roller 48 and the second heat source consisting of radiating type heater 56 are provided. Accordingly, when the monochromatic mode is selected, transfer paper 45 delivered from the transfer unit of dry type color copier is guided by guide plates 46, 47 to send to between fixing roller 48 and pressure roller 49 so that the toner is thermally fixed. Thereafter it is transported via guide plates 50W52 and transport belt 54 with suction fan 53, and exhausted from exhaust paper roller 55. When the full color mode is selected, the radiating type heater 56 starts, the transfer paper 45 is heated by the fixing roller 48, then heated by the radiating type heater 56 so that a good fixing is carried out.
