産業上の利用分野
本発明は、電子写真複写機の感光体面に残留し
ているトナーを除去したり、感光体面を帯電又は

するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to removing toner remaining on the photoreceptor surface of an electrophotographic copying machine, charging or eliminating electricity on the photoreceptor surface, and removing toner on the photoreceptor surface from paper. This relates to a brush used for transferring toner, peeling paper from the surface of a photoreceptor, and preventing toner stains.
従来の技術
パイル糸を基布にＶ織り、Ｗ織りなどのパイル
織りしたブラシが知られている。BACKGROUND TECHNOLOGY Brushes are known in which pile yarn is woven into a base fabric such as a V-weave or a W-weave.
発明が解決しようとする問題点
パイル糸を基布の地糸にて固定しているだけで
あるから、ブラシの回転、又は感光体等他の物と
の接触によりパイル糸の毛抜けが発生し易く、
種々の不具合を発生することがあつた。Problems to be Solved by the Invention Since the pile yarn is simply fixed with the base yarn of the base fabric, the pile yarn may come off due to rotation of the brush or contact with other objects such as a photoreceptor. Easy,
Various problems occurred.
例えば、感光体面上に残留しているトナーを除
去するために、前述のブラシを感光体面に接触さ
せた場合においてパイル糸が毛抜けすると、その
毛抜けしたパイル糸が感光体面上に付着して画質
障害等が起こると共に、毛抜けしたパイル糸がト
ナーとともに回収されるために、回収したトナー
を再利用する場合には、パイル糸が現像器内に混
入してトリミング不良やトナー詰りを起こして画
質障害となるなどの不具合を発生する。 For example, when the aforementioned brush is brought into contact with the photoconductor surface in order to remove toner remaining on the photoconductor surface, if the pile threads come off, the loose pile threads will adhere to the photoconductor surface. In addition to problems with image quality, the loose pile threads are collected together with the toner, so if the collected toner is to be reused, the pile threads may get mixed into the developing device, causing poor trimming or toner clogging. Problems such as image quality problems may occur.
なお、パイル糸の毛抜けを防止するためにパイ
ル織り裏面に樹脂等をコーテイングしたブラシが
存在するが、これによつてもパイル糸の毛抜けを
確実に防止できない。 Although there are brushes in which the reverse side of the pile weave is coated with a resin or the like to prevent shedding of the pile yarns, even this brush cannot reliably prevent the shedding of the pile yarns.
問題点を解決するための手段及び作用
基布の地経糸又は地緯糸に太さの異なる２種類
の糸を交互に組合せて、パイル糸を地経糸又は地
緯糸で強固に締め付けできるようにしたもの。Means and action for solving the problem Two types of yarns of different thickness are alternately combined with the ground warp or ground weft of the base fabric, so that the pile yarn can be firmly tightened with the ground warp or ground weft. .
実施例
第１図はブラシの一部分拡大斜視図、第２図は
第１図の−線断面図であり、パイル糸１は基
布Ａの地経糸２と地緯糸３とによつてＵ織から成
るパイル織りされている。なお、Ｗ織りとしても
良い。Embodiment FIG. 1 is a partially enlarged perspective view of the brush, and FIG. 2 is a cross-sectional view taken along the line -- in FIG. The pile is woven. In addition, W weave may be used.
前記地経糸２は大径（例えば400μ）の第１地
経糸２1と小径（例えば100μ）の第２地経糸２2と
を交互に織り込んであると共に、地緯糸３の太さ
は第１地経糸２1と第２地経糸２2との中間の太さ
となつている。 The ground warp 2 has a first ground warp 2 1 having a large diameter (for example, 400μ) and a second ground warp 2 2 having a small diameter (for example, 100μ). The thickness is intermediate between the warp 2 1 and the second ground warp 2 2 .
なお、地緯糸３の太さは前述のようにすること
が好ましいが、適宜の太さとしても良い。 Although it is preferable that the thickness of the ground weft 3 is as described above, it may be set to an appropriate thickness.
しかして、地経糸２が太さが異なる第１・第２
地経糸２1，２2より成つているから、基布Ａの詰
りが良くなつてパイル糸１が地経糸２に強固に締
め付けられるから、パイル糸１の毛抜けが防止で
きると共に、パイル糸１が根元から直立するため
にパイル糸１の高さにむらのないブラシとなる。 Therefore, the ground warp yarns 2 are the first and second yarns with different thicknesses.
Since the ground warp yarns 2 1 and 2 2 are made of the ground warp yarns 2 1 and 2 2 , the clogging of the base fabric A is improved and the pile yarn 1 is firmly tightened to the ground warp yarn 2 , which prevents the pile yarn 1 from falling out and prevents the pile yarn 1 from becoming loose. Since the pile yarns stand upright from the roots, the pile yarns 1 have an even height.
したがつて、感光体面上に残留したトナーを除
去するためにブラシを感光体面に接触した場合
に、パイル糸１の毛抜けがないから回収トナーに
パイル糸１が混入することがなく、回収トナー再
利用してもトリミング不良や、現像器内でのトナ
ー詰り等が無く、画質障害を発生することがな
い。 Therefore, when the brush is brought into contact with the photoconductor surface to remove the toner remaining on the photoconductor surface, the pile yarn 1 does not come off, so the collected toner is not mixed with the pile yarn 1, and the collected toner is Even if it is reused, there will be no trimming defects, toner clogging in the developing device, etc., and no image quality problems will occur.
また、パイル糸１が従来のブラシと比較して根
元から直立するために、ブラシの製造工程の内の
起毛工程が容易となると共に、ブラシをロール状
にした時に、その外径が均一化されるから、感光
体面上の残留トナーを除去するクリーニングブラ
シとして利用した場合に、クリーニング性のむら
が発生することがなくて良好なクリーニング性能
が得られる。 In addition, since the pile yarn 1 stands upright from the base compared to conventional brushes, the raising process in the brush manufacturing process is easier, and when the brush is rolled, its outer diameter is made uniform. Therefore, when used as a cleaning brush for removing residual toner on the photoreceptor surface, good cleaning performance can be obtained without causing uneven cleaning performance.
なお、第３図、第４図に示すように地緯糸３を
大径の第１地緯糸３1と小径の第２地緯糸３2とを
交互に織り込んでも、基布Ａのつまりが良くなつ
てパイル糸１が地緯糸３に強固に締め付けられる
から、パイル糸１の毛抜けが防止できると共に、
パイル糸１が根元から直立するためにパイル糸１
の高さにむらのないブラシとなる。 In addition, even if the ground weft 3 is woven alternately with the large diameter first ground weft 3 1 and the small diameter second ground weft 3 2 , the clogging of the base fabric A is improved. Since the pile yarn 1 is firmly tightened to the ground weft yarn 3, it is possible to prevent the pile yarn 1 from falling out, and
In order for pile yarn 1 to stand upright from the root, pile yarn 1
The brush will have an even height.
この場合には地経糸２は全て同一太さとなつて
いる。 In this case, all the ground warp threads 2 have the same thickness.
発明の効果
パイル糸１を地経糸２又は地緯糸３によつて強
固に締め付けできるから、パイル糸１の毛抜けを
防止できるブラシとなる。Effects of the Invention Since the pile yarn 1 can be firmly tightened by the ground warp yarn 2 or the ground weft yarn 3, the brush can prevent the pile yarn 1 from falling out.
