ABSTRACT:
A device for cleaning a transfer belt of an image-forming machine in which the transfer belt is wound around a drive roller and a driven roller that are disposed at a predetermined distance, in parallel with each other and is positioned opposite a photosensitive material drum in a transfer zone. A fur brush which has an electrically conducting property is rotated in contact with the surface of the transfer belt. A bias voltage is applied to the fur brush, the bias voltage having a polarity the same as the polarity for electrically charging the toner of a toner image formed on the photosensitive material drum. An opposed electrode is disposed opposite the fur brush and in contact with the back surface of the transfer belt.
