ている。First, in FIG. 1, as the fixing film 18 rotates in the direction of the arrow, the recording material sheet P is guided to the contact area between the heating member 14 and the pressure roller 21, that is, the nip N1, and the unfixed image is removed. is configured to be heated and fixed.

れている。Here, the heating body 14 is divided by a line 23 drawn in a vertical direction from the center of the pressure roller 21, and the side where the recording material sheet P enters is the upstream side, and the side where the recording material sheet P is ejected is the downstream side. . At this time, the radius of curvature R1 on the upstream side within the nip N1 is set larger than the radius of curvature R2 on the downstream side.
【００２２】これにより、ニップＮ１内の圧力分布は、

いるため、未定着画像は、上流側において急激な加圧を
受けずにすみ、画像の乱れも生じない。[0022] As a result, the pressure distribution within the nip N1 is as follows:
A gentle curve is drawn on the upstream side, reaching a peak at the boundary between the upstream and downstream sides, and a sharp curve on the downstream side, so the unfixed image is not subjected to sudden pressure on the upstream side. , no image disturbance occurs.

切である。[0023] At this time, the range of the radius of curvature R2 on the downstream side is appropriately 5 to 20 mm in order to have a curl removal effect and ensure the minimum nip width, and the range of the radius of curvature R1 on the upstream side is 5 to 20 mm. The larger the radius, the wider the nip width can be, but if it is too large, there is a possibility of damaging the inside of the fixing film 18, so 30 to 50 mm is appropriate.

場合には、前記Ｒ１は３０ｍｍ、Ｒ２は１０ｍｍにする
ことにより、ニップ幅Ｎ１は上流側で３ｍｍ、下流側で
１．５ｍｍ，合わせて４．５ｍｍとなる。For example, when applying pressure at 6 kg using a pressure roll 21 made of silicone rubber with a diameter of 20 mm and a hardness of 40 degrees, the nip width N1 is set on the upstream side by setting R1 to 30 mm and R2 to 10 mm. 3mm, 1.5mm on the downstream side, totaling 4.5mm.

で、合わせて３ｍｍとなる。したがって、上流側の曲率

とにより、ニップ幅Ｎ１を広くできる。On the other hand, as shown in FIG. 2, in the heating body 14 having a uniform radius of curvature, the radius of curvature R2 was set to 10 mm as on the downstream side in FIG. 1, and the same pressure roller 21 as above was used. In this case, the nip width N2 is 1.5 mm on both the upstream and downstream sides.
So, the total length is 3mm. Therefore, by setting the radius of curvature R1 on the upstream side to be larger than the radius of curvature R2 on the downstream side, the nip width N1 can be increased.

By being able to set
It is possible to improve fixing properties. On the other hand, if the conventional fixing performance is sufficient, an effect can be obtained in that the actual temperature control of the heating element 14 can be lowered by the increased nip width.

The shape of the heating body is a convex shape with downward curvature facing the pressure roller, and the radius of curvature on the upstream side is larger than the radius of curvature on the downstream side, so it is different from the conventional curved surface. The nip can be wider than that of a heater, making it possible to improve fixing performance without changing the temperature control, and also maintain the same effects as before, such as preventing downward curl and preventing internal damage to the fixing film. .
