に感光体ドラム１からトナーが転写される。(bl) Conventional technology In electrophotographic copying machines, etc., an electrostatic latent image is formed on the surface of a photoreceptor drum, toner charged by friction is electrostatically transferred to this electrostatic latent image, and further, A toner layer is formed on the transfer paper by electrostatically transferring the toner to a transfer paper whose back side is charged by a corona ion flow. Figure 3 shows the above process.
FIG. 2 is a diagram illustrating the configuration of a transfer device that executes a process of transferring toner to transfer paper. A charger box 2 is disposed opposite the photosensitive drum 1. A charge batting 3 is stretched inside the charger box 2. A high voltage is applied to this charge line 3 to generate a corona ion flow. A transfer sheet is conveyed from the sheet conveyance guide 4, and as the back surface of this transfer sheet is charged by the corona ion flow as described above, toner is transferred from the photoreceptor drum 1 onto the surface of the transfer sheet.

転写させることができるからである。(C) Problems to be Solved by the Invention When transferring toner to transfer paper in this way, it is possible that the toner will be transferred to the transfer paper after the transfer paper is brought into contact with the surface of the photoreceptor drum. desirable. This is because when the transfer paper comes into contact with the photoreceptor drum, the toner image formed on the surface of the photoreceptor drum can be reliably transferred to the transfer paper as is.

As shown in the figure, before the transfer paper A comes into contact with the surface of the photoreceptor drum 1, the back surface of the transfer paper A is charged by the roller ion flow, and this charged area and the surface of the photoreceptor drum 1 are electrically charged. Coulomb force is generated between the toner and the toner, and the toner may fly to the charged area of the transfer paper. As a result, toner scattering appears in the image formed on the transfer paper, resulting in a significant deterioration in image quality.

At times, the above-mentioned toner scattering occurs frequently, and at other times, it is impossible to obtain an image without scattering of I/toner, resulting in an unstable quality of the formed image.

することを目的とする。This invention prevents the transfer paper from being charged before it comes into contact with the surface of the photoreceptor drum, and also adjusts the distance between the paper conveyance guide and the photoreceptor drum to be appropriate depending on the stiffness (thickness) of the paper. An object of the present invention is to provide a transfer device that can obtain high-quality images without toner scattering, regardless of the stiffness (thickness) of the paper.

The regulation plate provided on the paper conveyance guide of the transfer paper is made of an insulating member, and the distance between the conveyance guide plate that guides the transfer paper to the contact point of the photoconductor drum and the photoconductor drum is approximately 1.011 or approximately. It is characterized by having a switching mechanism for switching to 2.0 fin.

ことが無くなる。(e) Effect In this invention, the region charged by the transfer charger is regulated by a regulating plate provided on the paper conveyance guide of the transfer paper, and only the area in front of the point where the transfer paper contacts the surface of the photoreceptor drum is charged. It becomes like this. Therefore, the transfer paper is not charged before it comes into contact with the photoreceptor drum, and toner does not fly to the transfer paper, improving image quality. In addition, by configuring the regulation plate with an insulating material, leaks do not occur between the charger wire and the regulation plate, and excessive current flows between the charger wire and the regulation plate, causing the charger line to become exposed to light. This eliminates the possibility that the transfer paper becomes difficult to be charged due to a decrease in the body drum current.

なる。Furthermore, the distance between the conveyance guide plate and the photoreceptor drum is switched by a switching mechanism, and the distance between the conveyance guide plate and the photoreceptor drum is changed to approximately 1.0 mm or approximately 2 mm.
Becomes 0 crane. Therefore, when the transfer paper is not stiff, the distance between the conveyance guide plate and the photosensitive drum should be set to about 1. By guiding the transfer paper to just before the contact point of the photoreceptor drum and bringing it into contact with the photoreceptor drum, the transfer paper comes into contact with the photoreceptor drum at the contact point. When using transfer paper with strong stiffness, the distance between the paper conveyance guide and the photosensitive drum should be approximately 2. 0mm, feed the transfer paper from the paper conveyance guide, and bring the transfer paper into contact with the contact point of the photosensitive drum. At this time, even if the distance between the paper conveyance guide and the photosensitive drum is about 2.0 mm, the transfer paper comes into contact with the contact point due to the stiffness of the transfer paper. In addition, when a transfer paper with a strong stiffness is used, if the above-mentioned interval is narrower than this, about <1.0 mm, the transfer paper will have a strong stiffness, and the transfer paper will be difficult to be contacted at the contact point.

The end of the paper conveyance guide 4 is slightly bent so as to face the photoreceptor drum, forming a flat piece 41. The transfer paper is guided by the paper conveyance guide 4 and is conveyed so as to come into contact with the photosensitive drum. Here, the point at which this transfer paper A is guided by the paper conveyance guide 4 and comes into contact with the photosensitive drum 1 is defined as a contact point P. If the transfer paper A is charged before the contact point P (on the left side in the figure) in the rotational direction of the photosensitive drum, the phenomenon of toner flying onto the transfer paper does not occur. Therefore,
A regulating plate 5 is adhered to the side of the flat piece 41 facing the photoreceptor drum. The regulating plate 5 is made of an insulating material such as polyethylene terephthalate (PET), and prevents the corona ion flow from the charge line 3 from being irradiated after the contact point P (on the right side in the figure).
