Abstract

전자사진 기록장치의 비자성 일성분 현상장치에 관한 기술이다.A non-magnetic one-component developing device of an electrophotographic recording device.

감광감광드럼(1)일측의 현상기 하우징(8)내의 탄성체결연롤러(3b) 표면에 도전성박막(3a)을 착한 현상롤러(3)와 밀착되게 현상제 공급롤러(4)를 설치하고 상기 현상롤러(3)상부에 현상제(7)층 규제 브랜드(5)가 설치된 상기 현상롤러(3)와 현상제 공급롤러(4)와 브래드(5)에 각각 고압부(9)를 전기적으로 연결구성하여 현상롤러상에 전계의 크기는 전기저항을 전원공브원과 도전성박막 사이에 부착하여 저항값을 조정하여 제어하도록하여 현상롤러의 신뢰성이 크게 향상됨과 동시에 종전의 고무롤러에 따른 어려움을 제거함으로써 저가의 신뢰성 있는 현상기 개발에 크게 기여함에 있는 것이다.A developer supply roller (4) is provided on the surface of the elastic binder roller (3b) in the developing housing (8) on one side of the photosensitive photosensitive drum (1) so as to be in close contact with the developing roller (3) having a conductive thin film (3a) thereon. (3) The high pressure part 9 is electrically connected to the developing roller 3, the developer supply roller 4, and the Brad 5, each of which has the developer 7 layer regulating brand 5 installed thereon. The size of the electric field on the roller allows the electrical resistance to be attached between the power source source and the conductive thin film to control the resistance value, thereby greatly improving the reliability of the developing roller and eliminating the difficulties caused by conventional rubber rollers. This is in large part contributing to the development of the present developing device.
