が低下してしまうという問題点があった。(Prior Art) A cleaning device for an electrophotographic device that uses a blade and a fur brush in combination to remove residual toner on a photoreceptor is well known. In this case, the fur brush has the function of actively removing or dispersing the toner, and in either case, it improves the margin of cleaning ability of the blade. However, as shown in FIG. 2, since the rotational direction A of the fur brush 1 and the rotational direction B of the photoreceptor 2 were the same, the residual toner 3 received force only in the rotational direction due to mechanical variations in the fur brush 1. If the length and density of the brush bristles vary due to deterioration over time, the residual toner 3' after passing through the fur brush 1 will become streaked in the direction of rotation. The problem is that the ability to deal with streaky residual toner is low, especially when the edges are worn, and the cleaning ability of the blade is reduced.
（目 的）

させる条件をファーブラシに与えることを目的としてい
る。(Objective) The present invention aims to provide the fur brush with conditions that improve the cleaning ability of the blade when the blade and fur brush are used together as cleaning means.
（構 成）
本発明は前記目的を達成するためファーブラシの回転方
向と感光体の回転方向とを所定角度に設定したことを特
徴とするものである。(Structure) In order to achieve the above object, the present invention is characterized in that the rotational direction of the fur brush and the rotational direction of the photoreceptor are set at a predetermined angle.
以下実施例に基づいて具体的に説明する。１０は入方向

プーリー１５と駆動プーリー１６と中間のアイドルコロ
１７間にタイミングベルト１８が懸架されている。Hereinafter, a detailed explanation will be given based on an example. 10 is a photoreceptor that rotates in the entrance direction. A fur brush 11 is set to rotate in a direction B inclined at a predetermined angle O with respect to the rotation direction A of the photoreceptor 10. The shaft 12 of the fur brush 11 is supported by bearings 13 and 14 of the machine body, and a timing belt 18 is suspended between a driven pulley 15 fixed to one end, a driving pulley 16, and an intermediate idle roller 17.
次に作用について説明する。感光体１０がＡ方向に回転
し、ファーブラシ１１がＢ方向に回転すると、ファーブ
ラシ１１から受けるカが残留トナーに対して角度０で作
用するので残留トナーがよく分散され、ファーブラシ通
過後の残留トナーは筋状にならない。なおファーブラシ
を軸方向に揺動させるようにしてもよい。Next, the effect will be explained. When the photoreceptor 10 rotates in the A direction and the fur brush 11 rotates in the B direction, the force received from the fur brush 11 acts on the residual toner at an angle of 0, so that the residual toner is well dispersed and Residual toner does not form streaks. Note that the fur brush may be oscillated in the axial direction.
（効 果）
本発明によるとファーブラシの回転方向と感光体の回転
方向とを所定角度に設定されているのでファーブラシ通
過後の残留トナーが感光体・上で筋状に残留せずブレー
ドにより極めて良好にクリーニングされる。(Effects) According to the present invention, since the rotating direction of the fur brush and the rotating direction of the photoconductor are set at a predetermined angle, the residual toner after passing through the fur brush does not remain in streaks on the photoconductor and can be removed by the blade. Cleans very well.
