ABSTRACT:
The aim of the present invention is to provide an image forming apparatus that accurately detects surface temperature of a rotating body using a noncontact temperature detection section and corrects the detected temperature according to the temperature of the surrounding area. The present invention detects the temperature of a thermal unit and the temperature of a holding unit and corrects the temperature of the thermal unit based on the temperature of the holding unit so that effects from the temperature of a surrounding area can be corrected and the temperature can accurately be detected without scarring a surface of the rotating body. Accurate regulation of the surface temperature of the rotating body can therefore be performed.
