動作を繰り返すようにしている。For example, the following image forming apparatuses are known. In other words, a charger is placed around the photosensitive material such as a photosensitive belt.
An image exposure section, a developing device, a transfer device, a cleaning device, etc. are arranged in sequence, and the surface of the sensitive material is charged with a charger, and then image exposed to form an electrostatic latent image. It is developed into a visible image by a developing machine, the visible image is transferred to paper by a transfer device, the paper is sent to a fixing device to fix the transferred visible image on the paper, and then it is applied to the surface of the photosensitive material. After the remaining toner is cleaned by a cleaning device, the toner is charged by a charger and the above-described operation is repeated.

装置が知られている。The cleaning device for the above-mentioned image forming apparatus has a brush roll and a blade arranged opposite to the photosensitive material, the brush roll is rotated to make sliding contact with the surface of the photosensitive material, and the blade is moved to the surface of the photosensitive material. A composite cleaning device is known that cleans residual toner and paper dust by contacting with the paper.

うにすることが好ましい。On the other hand, in the above-mentioned image forming apparatus, paper dust may adhere to the photosensitive material during the paper transfer/separation process and be carried to the cleaning device, and when this paper dust reaches the blade, it may cause contact between the tip of the blade and the photosensitive material. Since paper dust accumulates on the blade, and the cleaning performance of the toner by the blade is reduced, it is preferable to clean the paper dust with a brush roll to prevent it from reaching the blade.

For example, it is preferable to apply 250V or less.
次に具体例を説明する。Next, a specific example will be explained.

用と機械的力によって良好なりリーニング結果を得た。(Specific Example 1) A 15-denier brush bristles are made of conductive resin fibers with carbon dispersed in an acrylic base, and the brush bristles are 50.0 denier.
When testing the cleaning performance of paper powder by grounding a brush roll embedded in the core at a density of 00/1n2, the paper powder was (-) and the brush bristles were at zero potential, indicating that it was due to electrostatic action and mechanical Depending on the force, a good leaning result was obtained.

作用がより増大し優れたクリーニング結果を得た。(Specific Example 2) When testing the cleaning performance of paper dust by applying a (+) bias to the brush roll made of the brush bristles described above, it was found that the paper dust was (-) and the brush bristles were (+), so static electricity was detected. The action was further increased and excellent cleaning results were obtained.
次に第２実施例を説明する。Next, a second embodiment will be explained.
前述のように、樹脂中に炭素等を混合した導電性樹脂の
繊維より成るブラシ毛は剛性が通常の樹脂より成るブラ
シ毛に比べて若干弱く、ブラシ先端力が若干弱くなって
タルク掻き取り性が若干劣るので、ブラシ毛６を第３図
のように導電性樹脂より成る繊維１０と通常の樹脂より
成る繊維１１をよって１本とする。As mentioned above, brush bristles made of fibers made of conductive resin mixed with carbon, etc. are slightly less rigid than bristles made of ordinary resin, and the force at the tip of the brush is slightly weaker, making it difficult to scrape off talc. Since the brush bristles 6 are made of fibers 10 made of conductive resin and fibers 11 made of ordinary resin, the bristles 6 are made into one fiber as shown in FIG.
例えば、導電性樹脂より成る繊維１ｏをアクリル素地に
炭素を分散したものとし、通常の樹脂より成る繊維１１
をポリプロピレンとし、その２本の繊維によって１本と
することでブラシ毛とする。For example, a fiber 1o made of a conductive resin is made of an acrylic base with carbon dispersed therein, and a fiber 1o made of a normal resin is used.
is made of polypropylene, and its two fibers are combined into one to form brush bristles.

の掻き取りも良好であった。These brush bristles were implanted in the core to form a brush roll, and paper dust was cleaned by grounding the brush roll or by applying a (+) bias. In both cases, excellent paper dust cleaning results were obtained. Moreover, the stiffness of the brush bristles was improved and the force of the brush tip was increased, so talc could be scraped off well.
この場合、導電性樹脂より成る繊維１ｏと通常の樹脂よ
り成る繊維１１の表面積の比率を種々異ならせたところ
、５１対４９とすることが最も好ましいクリーニング結
果を得た。In this case, when the surface area ratio of the fibers 1o made of conductive resin and the fibers 11 made of ordinary resin was varied, the most preferable cleaning result was obtained with a ratio of 51:49.
例えば、アクリルに炭素を分散した１５デニールの繊維

クリーニング不良発生ストレステストをしたところ、第
４図に示す結果を得た。For example, when we conducted a stress test on the cleaning performance of paper dust and the occurrence of cleaning failures due to adhesion of paper dust, we conducted stress tests on the cleaning performance of paper dust and the occurrence of cleaning failures due to adhesion of paper dust, using different surface area ratios of 15 denier fibers made of acrylic with carbon dispersed and 17 denier fibers made of polypropylene. The following results were obtained.
この結果よりアクリル素地に炭素を分散した１５デニー

ポリプロピレンの１７デニール繊維を使用し、表面積比
率を４８対５２としたものが好ましい。From this result, it is most preferable that the ratio of 15 denier fibers with carbon dispersed in acrylic base to 17 denier fibers of polypropylene is 51:49 in terms of surface area, which is essentially 10 denier fibers with carbon dispersed in nylon. It is preferable to use 17 denier fibers of polypropylene and polypropylene with a surface area ratio of 48:52.
（１）ブラシ毛６が電荷を保持しないから紙粉とブラシ
毛６との静電気力によって紙粉をクリーニングできる。(1) Since the brush bristles 6 do not hold an electric charge, the paper dust can be cleaned by the electrostatic force between the paper dust and the brush bristles 6.
（２）ブラシ毛６が紙粉と逆極性に帯電されるから紙粉
とブラシ毛６との静電気力を大きくして紙粉をクリーニ
ングできる。(2) Since the brush bristles 6 are charged with a polarity opposite to that of the paper dust, the electrostatic force between the paper dust and the brush bristles 6 can be increased to clean the paper dust.
（３）ブラシ毛６の剛性が大となってブラシ先端力が大
きくなるので、紙粉のクリーニング性と同時にタルクの
掻き取り性も向上する。(3) Since the stiffness of the brush bristles 6 is increased and the brush tip force is increased, the cleaning performance of paper dust and the scraping performance of talc are improved.
