In electrostatic recording devices such as electronic copying machines, black fine powder called toner is generally used for image formation. Toner is usually mainly composed of a synthetic resin and a coloring agent such as carbon black, and is relatively light and has electrostatic properties, so it easily scatters and adheres to objects, staining the surrounding area and making it difficult to clean. Further, a magnetic material called a carrier used in combination with the toner is also in the form of fine powder, and there is a similar problem. During the production process or maintenance of an electrostatic recording device, it is necessary to clean the toner and carrier that adhere to the inside of the toner container such as the developing device, toner replenisher, and cleaning device, or that are scattered inside the recording device itself. These toner carriers are usually removed by suction using a hose connected to a vacuum source.

ない。 Figure 1 shows an example of a conventionally used suction hose, with a plastic flexible pipe 1.
An adapter 2 made of hard plastic and a pipe 3 made of the same material are attached to the tip, and a nozzle 4 made of soft plastic is attached to the tip. This hose connects the other end 5 of the flexible tube to a reduced pressure source and inserts the nozzle into the toner storage section or the toner scattering area to perform suction cleaning, but since it is entirely made of a non-conductive material, It is easy to generate static electricity and become charged due to friction with powder that is attracted at high speed. Particularly, the nozzle part, which is subject to high friction, is highly charged, giving a shock to the worker and causing spark discharge, resulting in work safety problems. As a solution to this problem, it is possible to make the nozzle part made of metal, but many of the objects to be cleaned are made of plastic, and metal nozzles cannot be used because they will damage these products.
本考案の目的は帯電による問題の発生しない粉

好ましい。 As the conductive soft material, it is preferable to use a conductive rubber having a specific solid resistance of 10 10 Ω-cm or less, which is based on rubber or various synthetic rubbers. Materials with a resistance of 10 10 Ω-cm or more have no effect in preventing static electricity. The electrical connection means for connecting the nozzle part and the grounding contact or terminal can also be made of a metal wire, wire mesh, etc. that constitutes the outer wall of the outer flexible hose of ordinary electric wires. From the standpoint of hose operability, etc., it is desirable to attach the above conductor wire inside the hose. Although the grounding contact or terminal may be provided anywhere on the hose, it is preferable for operation to be near the part where the hose is attached to the reduced pressure source. Most preferably, it is automatically grounded when attached to a vacuum source.

よい。 The powder cleaning hose according to the present invention can be used by connecting to a vacuum pipe connected to a large pressure reducing device or a small suction device such as a vacuum cleaner. It is preferable to have a structure in which a contact point connected to a grounding line is provided on the mounting portion and comes into contact with a grounding contact point of the powder cleaning hose. If such a grounding means is not available, a grounding terminal may be provided on the hose and the grounding line may be directly connected to this.

In FIG. 4, 41 is iron wire and 42 is plastic. Both ends of the threaded iron wire 35 constituting the flexible pipe are connected to the metal adapter 32 and the metal attachment member 36, respectively, and play the role of conductors, which has the advantage of eliminating the need for independent conductors. 33 and 34 are metal pipes and conductive rubber nozzles similar to those in Example 1, respectively.
