Abstract

A fixing device for fixing a toner image on a recording medium includes a heating roller, a fixing roller, an endless fixing belt extended around at least the heating roller and the fixing roller and configured to be heated by the heating roller, a pressing roller disposed opposite to the fixing roller via the fixing belt, a temperature detecting member configured to detect a surface temperature of the heating roller, and a control device configured to control a surface temperature of the fixing belt at a predetermined temperature based on a surface temperature of the heating roller detected by the temperature detecting member. The temperature detecting member contacts a circumferential surface of the heating roller where the fixing belt is not extended around, such that the temperature detecting member is held in a low frictional relation to the circumferential surface of the heating roller.
