摘要:
A cleaning apparatus for a liquid-development electrophotographic apparatus in which, after a toner image formed on a surface of an intermediate transfer member by use of a liquid developer is transferred to a printing medium, the liquid developer remaining on the intermediate transfer is removed and collected. The cleaning apparatus includes a cleaning-liquid application device for applying a cleaning liquid to the intermediate transfer member which has transferred an image to the printing medium; a bias voltage application device for applying a bias voltage opposite in polarity to charged toner particles of the developer to the intermediate transfer member; and a collection device for removing the cleaning liquid which has been applied to and the residual developer which remains on the intermediate transfer member from the intermediate transfer member without transfer of an image to the printing medium, and collecting the removed cleaning liquid and residual developer.
