る。Hitherto, heat fixing methods and apparatuses using Takaoka waves such as microwaves have already been disclosed in Japanese Patent Publication No. 49-38171, Japanese Patent Application Laid-Open No. 52-20039, and Japanese Patent Publication No. 54-10865. This high frequency heat fixing device is an excellent device that eliminates the following drawbacks in so-called external heat fixing pressure. In other words, it reduces the wait time until the temperature necessary for fusing is reached, eliminates the risk of fire, etc. that occurs when recording materials such as paper get stuck in the fixing area due to some accident, and furthermore This is a compact device that prevents wrinkles and image distortion caused by contact with heating rollers, etc.

面を近接搬送するものがある。Further, Japanese Patent Application Laid-Open No. 52-20039 proposes an apparatus for transmitting microwaves and transporting a recording material by passing it close to a waveguide that leaks the microwaves from a slit opening. Examples of this device include one in which the recording material is brought close to the waveguide surface by blowing air from a blower, and another in which the recording material is sucked by a suction device that sucks air inside the waveguide and conveyed close to the waveguide surface. be.

安定であるために不均一である。With devices like this that rely only on air blowing and suction means, it is difficult to apply enough energy to dielectrically heat the unfixed image on the waveguide that leaks microwaves due to unstable recording material transport. It is.

った。Furthermore, in the above device, since the conveyance rollers before and after the waveguide are parallel to and coincide with the waveguide surface in the MCC column conveyance direction,
Even when the recording material is blown or sucked, it may be conveyed in a wavy manner on the surface of the waveguide. Furthermore, when a recording material is conveyed close to a waveguide, the distance between the waveguide surface and the recording material often fluctuates. may occur. This phenomenon becomes particularly noticeable when unfixed images are fixed on plain paper materials having different recording media viscosity and thickness, resulting in an increase in unfixed areas and a decrease in fixing performance.

い場合があった。Furthermore, in the invention disclosed in JP-A-52-20039 mentioned above, in the embodiment in which the blower blows air from above the waveguide in the direction of the waveguide, the tip of the recording material supporting the unfixed image is・The rear end may float up due to the influence of air when being transported. Furthermore, when using suction using a suction device according to another embodiment, the leading and trailing ends of the recording material are similarly less likely to receive the absorption force, resulting in lifting and vibration. Therefore, in this invention, stable fixing performance may not be obtained in some cases.

吸引力を増大させることが考えられる。Furthermore, based on the invention disclosed in Japanese Patent Application Laid-Open No. 52-20039, the force blown by the proer or the suction force by the suction device is increased in order to prevent the tip and rear ends from lifting up, vibration, etc. as described above. It is possible that

周辺の空気流によって定着性が低下してしまった。However, with this configuration, the lifting and imaging of the leading and trailing ends of the recording material became more pronounced, and the conveying force of the recording material decreased. Furthermore, when the recording material is passed near the surface of the waveguide by relying only on this type of blowing force or suction force, not only the unfixed image is disturbed by the blowing force, but also the air flow around the waveguide etc. This resulted in a decrease in fixing properties.

と々る。In addition, with the above improvements, when the recording material passes over a high frequency application means such as a waveguide and is fixed, the recording material may not be conveyed smoothly or perturbations may easily occur in the conveyance of the recording material. However, the recording material does not receive uniform high-frequency energy at a distance from the high-frequency applying means with respect to the internal pressure in the thickness direction of the recording material, resulting in non-uniformity of fixing energy and an unfixed image.

The IFi microwave oscillator generates microwaves with an electric field component in the transmission direction 2. This microwave oscillator 1 is equipped with a magnetron that is more powerful than those used in household microwave ovens. The microwave application means has a waveguide and has a rectangular shape through which microwaves are transmitted in the direction of arrow 2. The exit side is higher than the entrance side. A slit 4 is formed on the 3-microwave application surface 3 on which the back surface of the recording material 7 on the image supporting side slides in a stable state.
For example, 45 degrees with respect to the conveyance direction 6 of the recording material 7 (specified in the figure)
A large number of them are arranged in parallel at an angle of . The slit 4 is formed diagonally to the conveying direction with a concave angle.
By providing this, microwaves can be applied to the entire surface of the recording material 7, and unnecessary leakage of microwaves can be suppressed.

It is slid and conveyed along the arrow AK above. The generator ll is actuated by the signal from the detection means 34, and microwaves are applied to the application surface 3.
Also leaks from slit 4. At the same time that the recording material 7 #-1 reaches the application surface 3 in this state, the recording material 7 is conveyed upward in the direction of arrow B while closely contacting the application surface. The front side of the recording material 7, which is conveyed in close contact with the recording material 7, is tilted upward relative to the rear side as it stably passes over the slit 4 through which microwaves leak in a nine-shaped pattern, so that the microscope image supported by the recording material T. is sufficiently dielectrically heated and completely fixed on the RF2 recording material 7.

At this time, after passing through the application surface 3, the recording material 7 is further conveyed between the pair of discharge rollers 8.9. Since the recording material 7 is conveyed upward in a curved manner, the rear side of the recording material 7 is brought into close contact with the application surface 3 without being lifted up. Therefore, the entire recording material 7 was conveyed in close contact with the application surface 3, and sufficient microwaves were applied to the entire visible image, making stable and reliable fixing possible.

Further, the angle formed by the straight line M connecting the rotation centers 8a and 9a of the rows 28 and 9 and the above extension line N is 1.190°, and the pressure contact portion t of the rollers 8 and 9 is located above the extension line P of the application surface 3.
