摘要： After passing a position of transfer to a printing medium 10, a portion of an intermediate transfer member 1 on which an image is previously formed reaches the position of a cleaning unit 2. The cleaning unit 2 removes residual toner, whereby the intermediate transfer member 1 prepares for a next cycle of formation of images in the corresponding colors by means of the developing units 4, 5, 6, and 7. The cleaning unit 2 includes an application friction roller 21 and a bias roller 24. The application friction roller 21 has a function to weaken cohesion/firm adhesion of residual toner through application of a cleaning liquid to the intermediate transfer member 1 and a function to exfoliate and disperse the residual toner in the cleaning liquid through imposition of a shear force on the residual toner. The bias roller 24 includes a bias voltage generation mechanism 24a for applying a bias voltage between the bias roller 24 and the intermediate transfer member 1. Application of a bias voltage weakens the force of adhesion of residual toner firmly adhering to the surface of the intermediate transfer member 1, whereby the residual toner exfoliates from the intermediate transfer member 1 and disperses in the cleaning liquid. The bias roller 24 is further adapted to collect the thus-exfoliated, dispersed residual toner.

摘要： An electrophotographic printing machine in which extraneous liquid developer material on a photoconductive belt (10) is substantially removed therefrom by a cleaning roller (48). A backup roller(49) is rotatively coupled to the cleaning roller (48) with the photoconductive belt (10) being interposed therebetween. The rollers are pressed into contact with the photoconductive belt. Either the photoconductive belt (10) or the backup roller is moved with movement of one frictionally moving the other. In this way, the cleaning roller and the belt move with the extraneous liquid material being removed from the belt.

摘要： An apparatus (48) in which residual toner is removed from a photoconductive surface (10) after the transfer of a developed liquid image from the surface to a copy sheet. A porous roll (56) or belt (96) is employed to disturb the residual toner and detach it from the surface. Suction or electrical forces, cooperating with the porous roll or belt, attract the detached toner thereto for removal from the photoconductive surface.
