Abstract

PURPOSE:To prevent image disturbance due to contacting with an unfixed face by applying a voltage to parallel electrode groups to attract electrostatically a transfer material through a semiconductive film and using transfer means independently of this operation to prevent contact with an unstable transfer face. CONSTITUTION:Forms 3 are sent to a transfer area one by one with a roll 1. Three color developed images of yellow, magenta, and cyan corresponding to an original picture are formed on photosensitive drums 4a-4c, and photosensitive drums 4a-4c and electrostatically attracting belts 9 in form carrying devices 8a-8c are rotated completely synchronously. Transfer means 7a-7c are used to transfer images onto the form 3, and a color copy of yellow, magenta, and cyan is obtained. Since the transfer material is carried surely without contacting mechanically one face of the transfer material, the image disturbance due to contacting with the unfixed face is prevented.

In electrophotography, a photoconductor such as a photoreceptor drum is generally charged in the dark, an original image is exposed to the photoconductor to obtain an electrostatic latent image, and this is developed. In high-speed machines, the developed image is transferred to a transfer material such as paper using a transfer means such as a roll to which a bias voltage is applied to obtain the object, but the image remains undefined until it is fixed in the next fixing process. The surface is in such an unstable state that it will come off if you touch it.

In particular, in the case of a copying machine that obtains color copies by transferring developed images of different colors onto a single sheet of paper multiple times, it is necessary to send such unfixed copies to the transfer area multiple times. Conventionally, in order to meet this requirement, the paper was held with a clipper and the paper was electrostatically attracted to a mesh-like drum, but this method resulted in image loss at the leading edge of the paper and Since the electrostatic adsorption of the paper does not have sufficient force, the rear part of the paper will be smeared, and if the unfixed surface comes into contact with other parts and is rubbed, the image will be distorted. In this case, it is possible to press and hold the unfixed surface using a star wheel, roller, or the like that has a small contact area, but even if this is done, image distortion will still occur.

The voltage to be applied is 5000V or less, preferably 1000V or less
A range of 2000V is used. This is set from the viewpoint of dielectric breakdown and the fact that if the moisture content of the paper (3) used is low, the suction is weak and a high voltage is required from this point of view. Furthermore, regarding the semiconductive film 07J, although it is better for the volume resistivity to be low for adsorption, if it is low, the power consumption will increase, and if it is too high, it will not work as a resistor and the adsorption force will be low. It is selected in the range of 108 to 1012 Ωcm. From a mechanical standpoint, its thickness is approximately that of a 05 dragon, for example. With this configuration, the suction force can quickly rise and fall.

As shown in Figure 1, the paper (3) is moved by the paper feed roller (1).
Therefore, each sheet is sent to five transfer areas. Photosensitive drum (4
In a) to (4c), developed images in eight colors of yellow, magenta, and cyan are created according to the original by means not shown, but the photosensitive drums (4a) to (4c) and the paper transport device (8a) The electrostatic adsorption belts (9) in ~(8c) rotate in complete synchronization, and the transfer means (7) is placed on the paper (3).
Transfer is performed one after another using a) to (7c), and yellow, magenta, and cyan toner images are superimposed to obtain a color copy. First, the paper (3) that has come out from the paper guide member (2) is transferred to the paper transport device (8a) after the developed image on the photosensitive drum (4a) is transferred onto the paper (3) by the transfer means (7a). It is electrostatically attracted and transported. Next, the sheet (3) is peeled off by a suitable peeling means, such as a belt neutralizer, a peeling claw, air blowing, etc., and sent to a transfer section consisting of a transfer means (7b), and the sheet (3) is further transferred to the next sheet conveying device (8b). will be in contact with.

When transporting the paper (3), the paper support and transport body of the paper transport device (8a) has the configuration shown in FIGS. 2 to 4, so in this embodiment, the paper is transported as shown in FIG. (3) The conveyance is performed in an upside down state, but even if it is upside down, it will be adsorbed and conveyed without falling. Also, at this time, it is inconvenient that the unfixed toner image is disturbed by the electrostatic field for attraction, but the paper (
The Coulomb force between the charge applied to the paper (3) and the charge of the toner attached to the paper (3) is so strong that it is unaffected by other electric fields, so it is not disturbed, and the experimental results also show that this is the case. It has not been. Furthermore, as mentioned above, the electrostatic adsorption belt (9), which serves as the supporting conveyor, supplies power only to the parts that require adsorption as shown in Figure 2, so the adsorption force suddenly decreases after passing the power supply area. Therefore, there is no problem with the insertion into the next transfer means (7b).

Also, JP-A-49-6218, JP-A No. 49-8953
The method described in Publication No. 7 electrostatically attracts paper to a highly insulating belt, and in this case, a high potential is required for attraction, resulting in dielectric breakdown of the photoconductor and paper falling from the belt. However, according to the above configuration, in order to support and convey the paper (3), a voltage of a different polarity is applied to every other electrode group arranged in parallel with the semiconductive film 0. This problem does not arise because the paper (3) is applied between the developed image and a transfer device, such as a corotron, which is provided separately from the developed image. The rise and fall of the suction force is extremely fast, unlike that of JP-A No. 49-6213, and therefore, the holding and peeling of the paper (3) on the conveying body is done at the processing speed of the copying machine. You can do it without any problem. Moreover, the transfer of the developed image is performed by a known means other than the conveyor as described above.

In the above embodiment, the case where there are a plurality of transfer sections has been explained as an example, but as mentioned above, it can also be applied to the case of a color copy system with only one transfer section, and the same effect can be applied. It is possible to eliminate image disturbances caused by contact with unfixed copies, which occurs in conventional color copying machines. That is, as shown schematically in FIG. 5, the supporting and conveying body shown in FIGS. 2 to 4 in the sheet conveying device (8) may be formed into a drum shape. In this case as well, it is possible to achieve the same purpose as in the above-mentioned embodiment, by applying voltage to the parallel electrode group and adsorbing the paper through the semiconductive film α2, and then flipping one side of the paper the necessary number of times. It is possible to transfer the developed image created by the developing means (171) by guiding it to the transfer area without mechanically touching it.
