It is.

を与える必要がある。Generally, in a copying machine that forms electrostatic IWgII'f, a photoreceptor, which has a photoconductive layer on a conductive substrate or an insulating layer thereon, is uniformly charged in the dark or while being exposed to light. , a surface potential is formed on the photoreceptor. Unnecessary portions of the formed surface potential are erased by a known method such as image exposure to form an electrostatic latent image. This electrostatic latent image is visualized by a known method using toner or the like, and the image density depends on the surface potential of the photoreceptor on which the electrostatic latent image is formed. Therefore, in a copying machine that forms an electrostatic latent image, it is necessary to apply a predetermined surface potential to the photoreceptor with good reproducibility in order to obtain copies with appropriate image density with good reproducibility.

に均一に帯電される。A charging corona discharge device that corona charges the photoreceptor with good reproducibility is a 5KV-10 charger applied to a thin wire provided near the surface of the photoreceptor layer.
The corona generated by applying a voltage of KV (fine wire force) ionizes air molecules and causes the ions to adhere to the surface of the photosensitive layer. FIG. 3 shows a perspective view of this charging corona discharge device 3, in which the discharge wire 31 has a diameter of 0.08 mm, for example.
A tungsten wire of mm l is stretched between the insulating side plates 33, and a high DC voltage is applied to the charging electrode. As a result, corona discharge occurs between the discharge wire 31, the surface of the photosensitive layer, and the back plate 32, and the photosensitive layer is uniformly charged.

した汚れｌ除去するには満足なものではなかった。Since a high voltage is applied to the discharge wire 314ζ,
Toner and airborne dust easily adhere to the discharge wire, and if toner or airborne dust or other foreign matter adheres to the discharge wire, the charging on the photoreceptor in that area becomes uneven, resulting in white streaks appearing on the image. Especially when the corona discharge is negative discharge compared to positive discharge, dirt on the discharge wire appears as white streaks on the image.For this reason, it is necessary to clean the discharge wire from time to time.In the past, the discharge wire was cleaned. In the past, wiping with alcohol-impregnated gauze or rubbing with a felt tip have been attempted, but these methods have not been satisfactory in removing dirt firmly adhered to the surface of the discharge wire.

きる放電ワイヤのクリーニング部材及びクリーニング方
法を提供することを目的とする。It is an object of the present invention to provide a cleaning member and a cleaning method for a discharge wire that can efficiently remove strongly adhered dirt without breaking the discharge wire by wiping or rubbing the discharge wire.

あることを発見した。The present inventor has developed wire brushes made of metal wire such as stainless steel, brushes made of resin hair, brushes made of animal hair such as pig hair, etc., using discharge wire as a cleaning member.
As a result of comparing and examining various changes in the number density, etc., it was discovered that the most efficient cleaning means is to rub with molded glass wool, rather than with a so-called brush-type flocked bristles.

本発明はグラスウール成形品の清掃効果について、子細
に検討したが、効率のよい清掃がなされる理由は次のよ
うなものと考えられる。The molded glass wool material is, for example, one in which glass fibers are mixed with an appropriate amount of a binder and pressed under pressure. Preferred molded glass wool materials include various types of Super Fine manufactured by Japan Inorganic Fiber Industry Co., Ltd. For example, S P

F-248, 8PF-264, 5PF-280, 5PF
-296, but as a result of experiments, it has a high density of 5PF-28
It was confirmed that 0.5PF-296 is better than lower density materials such as 5PF-224. (Density is Bulk Specific Gravity) In the present invention, the cleaning effect of glass wool molded articles has been studied in detail, and the reason why efficient cleaning is achieved is thought to be as follows.

周の何れの箇所に付着した異物もグラスウールと接触し
清掃される。(1) When the discharge wire rubs, the IC inside the glass wool molded product
In an intrusive way? Y! Since the glass wool is swept once, any foreign matter attached to any part of the outer periphery of the discharge wire comes into contact with the glass wool and is cleaned.
（２） グラスウールは電気的に絶縁性であるので、
摺擦中にグラスウールと異物との間で静電的な吸着力が
生じて清掃される。(2) Glass wool is electrically insulating, so
During rubbing, an electrostatic adsorption force is generated between the glass wool and the foreign matter, and the foreign matter is cleaned.
（３） グラスウールはガラス繊維が硬度と弾性とを
もっているので、放電ワイヤ表面に強固に付着した異物
も機械的に除去される。(3) Since the glass fibers of glass wool have hardness and elasticity, foreign matter firmly attached to the surface of the discharge wire can be mechanically removed.
