It is a transfer material.

ような問題を生じることがある。The applicant has previously eliminated the drawbacks of a transfer cloth suitable for use in multiple transfer type image forming apparatuses, particularly color copying apparatuses. That is, the problem was solved by increasing the capacity of the copying material when separating the insulating transfer material from the photoreceptor due to the presence of this conductive layer. When the transfer material provided with this conductive layer is used in a multiple transfer type image forming apparatus, particularly a color copying apparatus, it is possible to obtain a high quality multiple transfer image without transfer unevenness. However, depending on the conditions of this transfer material holding means, the following problems may occur.

。The first problem is as follows. In other words, a transfer material holding member, ie, a transfer drum, in a transfer device of a multiple transfer type image forming apparatus such as a color copying device is used to hold the leading edge of the transfer material to prevent the transfer material from shifting during multiple multiple transfer processes. A metal clipper is provided as a material gripping means. If the surface of the transfer material is conductive as described above, the surface of the transfer material will pass through the ripper and become grounded (hereinafter referred to as a leak state), and the transfer charge on the back surface of the transfer material will be blocked, and part or all of the image will be A so-called transfer failure phenomenon occurs in which the image is not transferred or the image density is reduced. In transfer materials with a surface resistance of 10 Ω or more, such as transfer materials coated with conductive resin on the surface of the transfer material, transfer defects only occur near the ripper.
For example, when a semiconductor thin film is provided on the transfer surface, the surface resistance is 10
In a transfer material having a conductive surface of Ω or less, transfer voids do not remain in the vicinity of the silica, but often occur over the entire surface of the transfer material because of the high degree of freedom of charge movement on the surface of the transfer material. Even if an insulating resin is coated on the surface of the metallic silica to prevent leakage, it is not possible to completely prevent leakage from the caltrop holes, and the durability of the coating film is also poor. There is a drawback.

一般の黒トナー。In addition, it is difficult to construct the silicon bar itself from a plastic material and insulate it from the standpoint of accuracy or strength of the device. The second problem that is undesirable is to apply a bias voltage to a metal silicate bar to prevent leakage because it makes the device complicated and expensive. be. Conventionally, when fixing a color toner image with a heat roller, the amount of silicone oil applied to the heat roller pair to prevent toner offset is as follows:

が困難となり、ジャムが発生し易かった。It is necessary to use an amount several times or more of the amount applied when fixing the image with a heat roller. This is because color toner is colored by heating and melting, so resins with a low melting point and high adhesiveness are generally used.Full-color images also require three times as much toner adhesion time as heavy-color images. This is due to the fact that there is. In this way, when fixing a color toner image with a heat roller, a large amount of silicone oil is applied to prevent toner offset, so when fixing a transfer material based on a polyester film, Heating D-ra of cola etc. and pressurizing D-ra of def.
- When the transfer material passes through a pair of rollers consisting of a roller, the gap between the front surface of the pressure roller and the back surface of the transfer material is filled with oil, and the transfer material is brought into close contact with the pressure roller, and heated. When the transfer material is softened, a force acts on the pressure roller side to curl the transfer material, making it difficult to separate the transfer material even with the action of the separating claw, and jams are likely to occur.
本発明の目的は上記の問題点に鑑み、クリッパーによシ
保持されたときにも転写ぬけを起させないことにある。In view of the above-mentioned problems, an object of the present invention is to prevent transfer omission even when held by a clipper.

バ−にリークし易いので問題がある。In FIG. 1(a), paper or the like 4 is adhered to the tip of the film 3 on the conductive surface 1 side. However, when using paper as the paper etc. 4, use low humidity (temperature 15C1 relative humidity 11 (2C1
) Sometimes the volume resistance is about 310 Ω・(7), which is no problem, but it is common (at a temperature of 20
C1 relative humidity 50%) or high humidity (35% relative humidity)
Sometimes the volume resistivity is about 10 Ω・α and about 10 Ω, respectively.
・This is a problem because it deteriorates the image quality and tends to leak into the green soba through the resistance of the paper, especially when it is humid.
従って、紙を紙等4として用いる場合は、全環境で良好

The transfer drum 7 has a large notch.A polyester mesh screen 9 of approximately 80 mesh is wrapped around the notch of an aluminum syringe 8. A metal sill bar 10 is provided to hold the tip of 3. Further, a discharge device 11 is provided inside the cylinder 8 to face the surface of a toner image carrier (not shown) for transferring images. Remove the transfer material from the tip of the paper by ripper 1.
It is held at 0 and wound around the transfer drum, and the rotation of the transfer drum is held at n? A toner image on a toner image carrier (not shown) is transferred thereto.

との分離が容易に行われるようになる。The paper, nonwoven fabric, or porous plastic film described above has oil absorption properties and has a rougher surface than polyester film, so when fixing is performed using a heated roller, it is necessary to After passing, the paper absorbs excess silicone oil and the surface roughness of the paper creates an air layer between the back surface of the paper and the surface of the pressure roller, reducing adhesion. This makes it easy to separate the paper or the like from the pressure roller.
