There is described a fixing apparatus for fixing a toner image onto a recording material, which makes it possible not only to reduce the frictional resistance generated between a temperature sensor and a heating member, but also to prevent occurrences of abnormal sounds and breaking of the wire coupled to the temperature sensor, both caused by the direct contact between them. The fixing apparatus includes: a heating member provided with a surface layer, which is elastically deformable and includes the paper sheet passing area and the paper sheet non-passing area; a pressing member that press-contacts the heating member; and a temperature sensor that contacts the paper sheet non-passing area of the surface layer. A surface roughness Ra of the paper sheet non-passing area is set at such a value that is larger than that of a paper sheet passing area.
