原因となっている。In an electronic copying machine, a device is known in which the toner remaining on the photoreceptor after transfer is scraped off with a fur brush or the like, and then conveyed again to a toner bottle or the current 1-section machine to be collected. Schematic diagrams of such a device are shown in Figures 2 and 3!
Shown in A. The toner removed from the photoreceptor by the cleaning device is sucked and collected by a cyclone 1 from a vacuum pump or the like, sent into a conveying pipe 3 by a rotary valve 2, and passed through the pipe 3 by an auger 4 to a toner bottle or It is transported to the developing machine. During the development and transfer process during the copying cycle, toner that adheres to the photoreceptor but is not transferred may have a reverse polarity, and is removed by a cleaning device and collected to be mixed with other normally charged toner. If mixed, normal toner will have opposite polarity, causing early deterioration of the toner.

。Also, if a lot of toner of opposite polarity is mixed in, it will repel toner of normal polarity and will easily cause clouds (toner flying up), causing capri in the background area of the resulting copy. , which causes dirt inside the aircraft.
このように従来の装置では逆極性の混入した回収トナー
をそのまま再使用しているために、良質の複写物が得ら
れなかったり、装置が汚れるという欠点があった。As described above, in the conventional apparatus, recovered toner mixed with the opposite polarity is reused as is, which has the disadvantage that good-quality copies cannot be obtained and the apparatus becomes dirty.
本発明の目的は、従来の欠点を解消し、回収したトナー

にある。SUMMARY OF THE INVENTION An object of the present invention is to provide a toner regenerating device that eliminates the conventional drawbacks and allows all collected toner to have the same polarity.

のとなる。[Means and effects for solving the problems] The present invention has the following features:
A toner regenerating device for an electronic copying machine is characterized in that a layer of a high-resistance material is provided on the inner peripheral surface of a pipe having a rotating auger inside for conveying toner collected by a cleaning device. In other words, a layer of high-resistance material is provided on the inner circumferential surface of the transport pipe on the path that transports the collected toner to the toner bottle or developing machine, and the toner moving in the pipe rubs against the high-resistance material layer to maintain the same polarity. It is designed to have The toner of opposite polarity that was mixed in the collected toner continues to rub on the high-resistance material layer, so that it becomes the same polarity as other toner of normal polarity, and when it is carried into the toner bottle or developing machine. All toners have normal polarity and are suitable for reuse.
実施例
以下に添付図面に基づいて本発明の１実施例を説明する

十分に帯電することができる。FIG. 1 is a longitudinal sectional view of the conveying pipe 3, and the inner circumferential surface of the pipe 3 is provided with Teflon 5 as a high-resistance material. This conveying pipe 3 communicates between the cleaning device and the toner bottle or the developing machine, and an auger 4 is rotatably provided in the pipe 3, and the collected toner is conveyed by the auger 4. The surface of Teflon 5 has a lot of friction (when toner slides on this surface, the toner is charged by the friction with Teflon 5, and all the toner has the same polarity. Due to the friction with Teflon 5 Toner with normal polarity has a large amount of m-electrode, and toner with opposite polarity has normal polarity.The thickness of the Teflon layer 5 is thin (even if it is only a few tens of microns, the toner can be sufficiently charged by rubbing). I can do it.
本発明において使用する高抵抗材料はテフロンに限られ
るものではなく、トナーが摺擦して摩擦帯電゛するもの
であればよい。The high-resistance material used in the present invention is not limited to Teflon, but may be any material that is triboelectrically charged when the toner rubs against it.

し、再使用に好適なものとなる。When the toner is transported through the pipe whose inner surface is coated with Teflon, it is charged to the normal polarity due to friction with the Teflon, and has the same properties as fresh toner, making it suitable for reuse.

る。According to the apparatus of the present invention, all the collected toner is charged to the normal polarity and no toner of the opposite polarity is mixed in, so that cloud formation is prevented and high-quality copies without capri are obtained. be able to. Furthermore, the developer does not deteriorate early (and image density decreases can be prevented).
