Patent ID: 8068749

Claim:
A fixing apparatus, in which a recording material is caused to pass through a nip portion formed by contact between a rotating hot roller and a rotating pressure roller such that an unfixed image on the recording material becomes fixed, comprising: a heating belt that contacts and rotates with the hot roller and that conducts heat to the hot roller, a first support roller and a second support roller that are provided with a heat source, are heated by the heat source, support the rotating heating belt suspended therebetween, and rotate to conduct heat to the heating belt, a first temperature detection means that detects a first temperature, which is a temperature of an area of the first support roller where it contacts the heating belt or an area of the heating belt where it contacts the first support roller, a second temperature detection means that detects a second temperature, which is a temperature of an area of the second support roller where it contacts the heating belt or an area of the heating belt where it contacts the second support roller, and a means for detecting rotation stoppage of one of the support rollers that detects a rotation stoppage of one of the support rollers, which is a rotation stoppage of one of the first support roller and the second support roller, by comparing the first temperature and the second temperature.
