Abstract:
1. A fixing apparatus, comprising: a heating rotating member for fixing a toner image on a sheet of paper by heating; a first detection portion for detecting a temperature of an atmosphere attained by heat conduction from said heating rotating member as a first detected temperature; a second detection portion for detecting a quantity of infrared rays radiated from said heating rotating member; a heating portion for heating said heating rotating member; and a control portion for controlling heating by said heating portion based on said first detected temperature from said first detection portion and a second detected temperature corresponding to the quantity of infrared rays from said second detection portion, said first detection portion detecting a temperature at a position above said heating rotating member, and said second detection portion detecting a temperature at a position below said heating rotating member, wherein said control portion corrects said second detected temperature based on said first detected temperature.
