Claims (1)
の残留トナーを吸着除去するようにした導電性繊
維からなるフアーブラシと、該フアーブラシの下
流位置にて上記感光体上の残留トナーを掻き取る
ようにしたリーデイング方式のブレードとを組み
合わせた構成を有するクリーニング装置において
、上記フアーブラシから感光体の間に流れる電流
が＋２０μＡ以上になるように印加バイアスを設
定したことを特徴とするクリーニング装置。 A fur brush made of conductive fibers that adsorbs and removes residual toner on the photoreceptor by applying a bias of opposite polarity to the toner, and a fur brush that scrapes off the residual toner on the photoreceptor at a position downstream of the fur brush. What is claimed is: 1. A cleaning device having a configuration in which a leading type blade is combined with a cleaning device, characterized in that an applied bias is set so that the current flowing between the fur brush and the photoreceptor is +20 μA or more.
