摘要： 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.

摘要： The rotating speed of the coating brush of the image forming apparatus fluctuates between the upper limit speed and the lower limit speed across the standard speed. Consequently, the positional relation of the contact between the brush textile of the coating brush and the surface of the photographic sensitive drum varies for a wider range compared to a case where the rotating speed of the coating brush does not vary. Since the thin area of the brush textile moves for a wider range of the surface of the photographic sensitive drum in the axial direction of the rotating shaft of the photographic sensitive drum, the area where the coating amount of the lubricant is less is evened out by the area where the coating amount of the lubricant is rich, thus improving the unevenness of coating of the lubricant on the photographic sensitive drum.
