回転ドラムの外周面に近接する現像電極を備えた
電子写真用湿式現像装置において、前記回転ドラ
ム外周面の感光体の回転後方部にドラム電極を設
け、該ドラム電極が前記現像電極に近接した状態
で、現像電極に付着するトナーと逆極性の電位を
前記ドラム電極に印加するように構成したことを
特徴とする電子写真用湿式現像装置。 In an electrophotographic wet-type developing device comprising a rotating drum that holds a photoreceptor on its outer circumferential surface, and a developing electrode close to the outer circumferential surface of the rotating drum, a drum electrode is provided on the outer circumferential surface of the rotating drum at a rotationally rearward portion of the photoreceptor. A wet type developing device for electrophotography, characterized in that the drum electrode is configured to apply a potential having a polarity opposite to that of the toner adhering to the developing electrode to the drum electrode in a state where the drum electrode is close to the developing electrode.
