METHOD AND DEVICE FOR CLEANING LIQUID DEVELOPMENT ELECTROPHOTOGRAPHIC DEVICE

摘要

A cleaning unit 2 has a coating friction roller 21 and a bias roller 24. The coating friction roller 21 performs the function of coating an intermediate transfer body 1 with a cleaning liquid to weaken the coagulation/adherence of the remaining toner and the function of imparting a shearing force to the remaining toner to release it for dispersion in the cleaning liquid. Further, the bias roller 24 has a bias voltage producing mechanism 24a for applying a bias voltage between itself and the intermediate transfer body 1. The application of bias voltage causes the remaining toner adhering to the surface of the intermediate transfer body 1 to have its adhering force weakened for release from the intermediate transfer body 1 and dispersion in the cleaning liquid. Further, the bias roller 24 collects the released and dispersed remaining toner.
