摘要： A sheet reversing apparatus which has a take-in path, a reversing path which extends from the take-in path in a substantially same direction, a take-out path which extends from a junction of the take-in path and the reversing path in a substantially perpendicular direction to the extending direction of the reversing path. A sheet is fed from the take-in path to the reversing path, and when the trailing edge of the sheet comes out of the take-in path, the sheet is fed back from the reversing path to the take-out path. In an entrance portion of the reversing path, a first reversing roller which is driven to rotate in a feed-back direction toward the take-in path and a second reversing roller which is capable of coming into contact with and moving away from the first reversing roller are provided. The second reversing roller is away from the first reversing roller until the trailing edge of a sheet comes out of the take-in path, and comes into contact with the first reversing roller after the trailing edge comes out of the take-in path.

摘要： A fixing apparatus includes a fixing belt that pressure-thermally fixes unfixed toner images on sheets, and an oil coating roller that holds silicone oil for preventing the offset phenomenon to be coated on the fixing belt. The oil coating roller consists of an inner oil holding layer formed of paper and a surface oil holding layer formed of aramid fibers. The oil diffusing capacity and the oil holding capacity are reduced from the inner oil holding layer toward the surface oil holding layer. Thus, it is possible to suppress the oil coating amount in the initial period of the roller life to a level that does not cause problems such as oil stains, increase the oil coating amount in the final period of the roller life to a level that does not cause problems such as offsets, and prevent image noises.
