ABSTRACT:
A a fixing apparatus for an electrophotographic apparatus includes a heat roller (11a) having a heater (14) therein and a pressure roller (11b) urged against the heat roller, wherein a recording material (6) holding a toner image (25) thereon is sandwiched and carried while being heated and pressurized at a pressing portion between the heat roller and the pressure roller thereby to fix the toner image on a surface of the recording material, the fixing apparatus further including a first temperature detecting mechanism (18) formed by a temperature detecting element (15) provided at a portion of an outer periphery of the heat roller and a sensor head (17) disposed so as to be able oppose to the temperature detecting element, a second temperature detecting mechanism (19) formed by a plurality of temperature detecting elements disposed at a constant interval therebetween along an axial direction of the heat roller and spaced from the outer periphery of the heat roller, and a control mechanism (20, 21, 22, 23, 24) for controlling turning-on and turning-off of the heater in accordance with either one of outputs from the first and second temperature detecting mechanism.
