Conventional Structure and Problems Generally, in a 1E photocopying apparatus, a drum-shaped or belt-shaped light body is charged with a charger and exposed to light to form an electrostatic latent image. This is developed with toner, and with the transfer paper in contact with the developing surface of the photoreceptor surface, a transfer charger applies a corona discharge of opposite polarity to the charge held by the toner to the transfer paper, and the developed toner image is created. Transfer it to transfer paper. Next, in order to separate the transferred transfer paper from the photoreceptor, a separation charger is used to apply an alternating current corona discharge.
When the charge on the transfer paper and toner white that is charged during transfer is removed, the rigidity of the transfer paper is naturally separated from the photoreceptor by its own weight. This transfer paper is guided to a fixing device by a fixing guide, and the toner image is fixed on the transfer paper.

Although the configuration described above is a general electrophotographic copying machine, there is a growing trend to simplify the configuration of copying machines and commercialize small, inexpensive products, and the above-mentioned configuration of the copying machine has been simplified.
Charging and transfer are performed in one charge-1'
A copying machine has been proposed that removes the separation chips 4, 4, and 4, and also removes the AC high voltage power source. FIG. 1 shows such a conventional example. As shown in FIG.
The transfer paper 2 guided by the belt-like photoreceptor 1 attached to the photoreceptor 1 attached to the photoreceptor 1a and Ii and the light-driven roller 1b is charged and transferred with a toner image formed on the surface of the belt-like photoreceptor 1 by the image forming means. Transfer by step 4. Next, the transfer paper 2 and the belt-shaped photoreceptor 1 advance at the same speed, and when the leading edge of the transfer paper 2 reaches the 118 light body driven roller 1b, 1
(Since the curvature of the 8-light driven roller 1b is steep, the transfer paper 2 advances by 1%j due to this curvature due to the rigidity of the transfer paper 2, and at this curvature part, the transfer paper 2 moves from the belt-shaped photoreceptor. The transfer paper 2 and the belt-shaped body 1 are separated.
As the transfer progresses, the front section 11 of the transfer paper 2 moves downward due to its own weight, contacts the fixing guide 5, advances further, is guided by the fixing device 6, and the toner image is transferred. It is fixed on the paper 2.

However, when performing so-called double-sided copying, in which the transfer paper that has been copied once is turned over and copied again, the toner image on the belt-shaped photoreceptor 1 is transferred to the transfer paper 2 at the moment it contacts the fixing guide, as shown in FIG. There has been a problem in that the transferred unfixed toner image is scattered, which is so-called image disturbance. Therefore, the current situation was that double-sided copying was not possible. This development does not occur in a conventional copying machine configuration in which charges are removed from the transfer paper and toner after transfer using an 11 charger. '8: Well, the common flaws in the copying machine configurations that cause these image disturbances are:
1 ii 11 Separating the transfer paper from the light body without using a charger [1] In other words, a separation belt,
Separation claw: There is also a method of increasing the curvature of a portion of the photoreceptor described in the prior art example and naturally separating the transfer paper at that portion. The common point between these is 1 (^
The white of the transfer paper after transfer is electrically charged by the transfer so that it separates from the photoreceptor without being transferred. This method has the disadvantage that image disturbance occurs in which one unfixed toner image is skipped, and high-quality TI screen copying cannot be performed.

Which double-sided copying causes image disturbance? 111d:
After the transfer, the heat from the first fixing removes moisture from the transfer paper, increasing the resistance value of the transfer paper itself and increasing the amount of charge. Therefore, when this transfer paper is used as double-sided copying paper, the amount of charge accumulated on the transfer paper during the second transfer increases significantly compared to the first transfer, so this transfer paper When the i3 light body contacts the fixing guide, the charge on the transfer paper is rapidly removed, and at that moment, unfixed toner on the transfer paper scatters, causing image disturbance. Therefore, image disturbance does not occur in the first copying, but image disturbance occurs in the second copying (double-sided copying) because of the amount of charge that the transfer paper after the area C from the photoreceptor has, in other words, the fixing guide. This is because the charge change needle that is removed when the transfer paper comes into contact with the transfer paper is thick. Image disturbance under normal conditions, l'1. (u) This occurs during double-sided copying, but when polyester notebook paper with a high resistance value is used as the transfer paper, 1. Image disturbance occurs even during the first copying. Therefore, attempts have been made to manufacture transfer paper by controlling its resistance value, but these have had drawbacks such as increased manufacturing cost of the transfer paper. Another conventional example that solves these drawbacks is shown in FIG. In FIG. 2, one part is a belt-shaped photoreceptor using an organic photoconductor. This photoreceptor uses a polyester film as a paste, and a photosensitive layer is provided on the surface of the film. This belt-shaped photoreceptor 1 (hereinafter referred to as photoreceptor) is mounted on a photoreceptor driving drum 1a and a photoreceptor driven roller 1b so that it can be driven. The transfer paper 2 is guided to the photoreceptor 1 by the transfer guide 3, and the toner image formed on the surface of the photoreceptor 10 by the image forming means is transferred by the charging and transfer charger 4.

Next, the transfer paper 2 and the photoconductor 1 advance at the same speed, and when the leading edge of the transfer paper 2 reaches the photoconductor driven roller 1b, the iK advance due to the rigidity of the transfer paper 2 changes due to the change in the curvature of the photoconductor. The transfer paper 2 overcomes the electrostatic adsorption force between the transfer paper 2 and the photoreceptor 1 and separates from the photoreceptor 1 at the photoreceptor driven roller 1b. When the transfer paper 2 and photoreceptor 1 further advance, the transfer paper 2
The straightness due to the Jril property of the transfer paper 2 is prevented from leaking due to its own weight, and the leading edge of the transfer paper 2 moves downward. This transfer paper 2
The fixing start point of the fixing device 6 is provided before the leading edge of the fixing device 6 traces the downward line. That is, the photoconductor driven roller 1b and the fixing device 6 are brought close to each other.

However, although this conventional example can prevent image blurring, it is necessary to place the photoreceptor driven roller and the fixing device close to each other as described above. As a result, the secondary qj heat from the fixing device causes the temperature of the photoconductor to increase significantly, and if the copying machine is used continuously for a long time, 1! In addition to increasing li', the polyester film that is the base of the 1-tooth photoreceptor is deformed by the heat, the circumference of the belt-shaped photoreceptor is extended, and the 11'8 photoreceptor becomes slack. Slips may occur, which may impede the photoreceptor drive and make it impossible to use. Unfortunately, cracks occur in the photosensitive layer due to deformation of the base film, significantly reducing image quality.
