Further, the side plates 201A and 201B are provided with an insertion opening 210 into which the air blowing unit 16 is inserted.

Next, a holding structure for holding the first end of the heating roller unit on the side plate will be described with reference to FIGS. 7 to 13. FIG. FIG. 7 is a perspective explanatory view of the main part of the heating roller unit with the first end portion held by the side plate, and FIG. 8 is a perspective explanatory view of the first cylindrical holding portion of the side plate. 9 is a front view of the heating roller unit, FIG. 10 is a perspective view of the first end of the heating roller unit, FIG. 11 is a perspective view of the internal portion of the first end, and FIG. FIG. 4 is an enlarged explanatory view of a main portion of one end; FIG. 13 is also a cross-sectional explanatory view of the fitting state between the first end portion and the first cylindrical holding portion of the side plate.

A first cylindrical holding portion 202A for holding a first end portion 302A of the heating roller unit 301 is fixed to one side plate 201A.

The heating roller unit 301 includes the heating roller 11, side plates 311A and 311B, which are holding plate members to which bearings that rotatably hold both ends of the heating roller 11 are attached, and stays that connect the side plates 311A and 311B. 312.

A circular member 313A is fixed to the side plate 311A. A lamp holding member 316A is attached to the circular member 313A and holds two heater lamps 317 arranged inside the heating roller 11 with the lamp holding member 316A. A static elimination brush holder 318 holding a static elimination brush 319 is attached to the circular member 313A.

At the first end portion 302A of the heating roller unit 301, a fitting member 321 that fits with the first tubular holding portion 202A is arranged outside the fitting member 321 in the axial direction. and a tapered profile member 331 extending therein.

The fitting member 321 is fixed with a screw 329 to the circular member 313A. The fitting member 321 forms a fitting portion 322 provided with a plurality of protrusions 324 that come into contact with the inner peripheral surface 214 of the first cylindrical holding portion 202A. Further, the fitting member 321 has, on the circular member 313A side of the fitting portion 322, an abutting portion 325 formed of a stepped portion that abuts against the axial end surface 215 of the first cylindrical holding portion 202A.

Here, by providing the fitting portion 322 with the protrusion 324, the fitting portion 322 can be easily fitted into the first cylindrical holding portion 202A, and the heat roller 11 can be moved in a direction orthogonal to the roller axis of the heating roller 11. can be easily determined.

Further, by providing the abutment portion 325 formed of a stepped portion abutted against the end surface 215 of the first cylindrical holding portion 202A, the heating roller 11 can be accurately positioned in the roller axial direction.

The length of the projection 324 of the fitting portion 322 of the fitting member 321 is determined so that the projection 324 reaches the first tubular holding portion 202A at the final timing of inserting the fitting member 321 into the first tubular holding portion 202A. The length is such that it is fitted to the inner peripheral surface 214 of 202A. In addition, the protrusions 324 of the fitting portion 322 of the fitting member 321 are arranged at four locations in the circumferential direction to smoothly fit the fitting portion 322 to the inner peripheral surface 214 of the first tubular holder 202A. I am making it possible.

The tapered member 331 is secured to the fitting member 321 with a screw 339 or the like. The tapered shape member 331 forms a tapered shape portion 332 that enters into the first cylindrical holding portion 202A.
