問題がある。In the conventional recording apparatus as described above, if the transfer of the toner image on the toner image forming body to the intermediate transfer body depends on the adhesive force by pressure contact, the intermediate transfer body may be made of silicone rubber, fluorine rubber or the like. A material having an elastic layer on the surface is used. When the transfer is performed electrically, an intermediate transfer member having a conductive layer under the surface layer such as a fluorine rubber layer or a fluorine resin coating layer is used. A bias voltage of about 1 kV is applied to the formed body, and the pressure roller of the recording transfer unit has a surface made of metal with good thermal conductivity, or a relatively thin heat-resistant resin A layered type is usually used. Then, since toner remains on the intermediate transfer body and the pressure roller, a cleaning member such as a cleaning roller, a blade or a brush is attached to the intermediate transfer body and the pressure roller from the recording transfer section in order to remove it. It is provided on the downstream side. As described above, when the cleaning member is provided on the intermediate transfer body, there is a problem that the surface of the intermediate transfer body is easily scratched and the performance is easily deteriorated.

ける必要が生ずる場合もある。Here, when the recording apparatus is based on the electrophotographic method, the toner image forming body 1 has an electrophotographic photosensitive layer on the surface, and the latent image forming part 2 has a charging mechanism for uniformly charging the surface of the photosensitive body. An image projection mechanism for performing image exposure on the charged surface is provided. Further, when the recording apparatus is based on the electrostatic recording method, the toner image forming body 1 has a dielectric body including a dielectric substrate and a dielectric surface layer on the surface,
The latent image forming unit 2 is provided with, for example, a multi-stylus electrode or an ion control electrode that forms an electrostatic latent image on the surface of a dielectric according to an image forming signal. When the recording apparatus is based on the magnetic recording method, the image forming body 1 has a magnetic material on the surface, and the latent image forming section 2 forms a magnetic latent image on the magnetic material surface according to the image signal. It will be equipped with a magnetized head. When the latent image formed on the toner image forming body 1 is an electrostatic latent image as described above, the toner phenomenon portion 4 charges the toner to the opposite polarity to the electric charge of the electrostatic latent image to form the toner image forming body 1. The toner image forming member cleaning unit 11 has a discharging mechanism for discharging the surface of the toner image forming member 1 and a toner removing mechanism for removing the residual toner so that different latent images can be formed next. Be prepared. When the latent image is a magnetic latent image, the toner phenomenon portion 4 supplies magnetic toner to the surface of the toner image forming body 1, and the toner image forming body cleaning portion 11 removes the degaussing head and the residual toner. And with. The respective structures based on the differences in the recording method as described above are conventionally known. The intermediate transfer member 5 and the pressing roller 6 have the same structure as in the conventional recording apparatus. , Which preferably has an LTV or RTV type silicone rubber layer, and whose pressing roller 6 has a less releasable substance to the toner on the surface layer, preferably HT.
It has a V-shaped silicone rubber layer. The pressure roller 6 does not have an HTV type silicone rubber surface layer, and the surface is A
It may be made of a metal such as l or stainless steel or a heat resistant resin such as polyimide. These materials also exhibit the advantageous property of being less releasable from the toner. Such a pressing roller 6 also functions as a cleaning roller by directly contacting the intermediate transfer member 5 with pressure when the recording paper P is not fed. However, the intermediate transfer member 5
In order to perform the cleaning completely, the cleaning by the pressing roller 6 may not be sufficient in some cases, and it may be necessary to additionally provide the cleaning member 9 as shown in the drawing.

リーニング効果が向上する。In the present invention, in order to improve the cleaning effect of the pressing roller 6 on the intermediate transfer member 5, the intermediate transfer member 5 is moved during the recording operation other than transferring the toner image on the toner image forming member 1 to the intermediate transfer member 5. Separated from the toner image forming body 1,
During that time, the intermediate transfer member 5 is cleaned by the pressing roller 6. As a result, the intermediate transfer body 5 is cleaned by the pressing roller 6 in a state where the toner image is not transferred from the toner image forming body 1, so that the cleaning load on the pressing roller 6 is reduced and the cleaning effect is improved.
このような中間転写体５のクリーニングの態様（主とし
てクリーニング時間に関して）には次のようなものがあ

行う、等である。(A) The intermediate transfer body 5 is separated from the toner image forming body 1 for cleaning in each recording cycle, and (b) the intermediate transfer body 5 is cleaned during the recording operation.
Of course, cleaning is performed during this period, but when the recording operation is completed, the intermediate transfer body 5 is separated from the toner image forming body, cleaning is performed in this state, and the surface of the intermediate transfer body is cleaned for the next recording operation. (C) Prior to the recording operation, the intermediate transfer body 5 is separated from the toner image forming body 1 and cleaning is performed in this state, and then the recording operation is performed. Of course, cleaning is performed during the recording operation.
なお、上記（ａ）（ｂ）（ｃ）いずれの場合において

体１から離れたクリーニングを行い、トナーがトナー像
形成体１から中間転写体５に移らない状態で中間転写体
５の前表面がクリーニングされるようにするのが望まし
い。In any of the above cases (a), (b), and (c), cleaning is performed away from the toner image forming body 1 while the intermediate transfer body 5 makes at least one revolution, and the toner is removed from the toner image forming body 1 to the intermediate position. It is desirable that the front surface of the intermediate transfer body 5 be cleaned without being transferred to the transfer body 5.

与える。Since the toner attached to the pressing roller 6 while the intermediate transfer member 5 is being cleaned is removed by the cleaning member 8 of the pressing roller 6, the heating pressing roller 6 contaminates the back surface of the recording paper P with toner. There is nothing to do. Also,
While the recording paper P is passing through the transfer fixing section b,
The recording paper P serves as a cleaning member for the intermediate transfer body 5. Therefore, according to the method of the present invention, it is not necessary to provide a cleaning member on the intermediate transfer member 5, and even if it is provided, an auxiliary weak cleaning action can be provided. Therefore, the possibility of damaging the intermediate transfer member 5 can be eliminated. The heater 10 also serving as a guide is mainly for improving the transfer fixing efficiency on the recording paper P, and by providing it, it is possible to further eliminate the need to provide a cleaning member on the intermediate transfer member 5, or to replace the cleaning member with a cleaning member. The action can be reduced. The pressing roller 6 and, if necessary, the intermediate transfer member 5
It is preferable that the cleaning members 8 and 9 provided in the above are composed of rollers as shown in the drawing, since the surfaces of the pressing roller 6 and the intermediate transfer member 5 are less likely to be damaged, and in order to improve cleaning efficiency, they are heated. Means may be provided. Further, in the present invention, the toner image forming body 1 and the intermediate transfer body 5 are not limited to the drum or roller type, but may be the belt type, and the intermediate transfer body 5 has a heating means. You can buy it. And the intermediate transfer member 5
Is separated from the toner image forming body 1 because the intermediate transfer body 5
Not only in the cleaning effect, but also to prevent the temperature of the toner image forming body 1 from rising due to the heat transfer from the intermediate transfer body 5, and in particular, to prevent the deterioration of the characteristics when the toner image forming body 1 is a photoconductor. It also has an effect of preventing or fusing of the toner in the phenomenon portion, the transfer portion and the like.
