More Information
Summary:A cleaning roll for a xerographic cleaning station is disclosed. The roll may comprise a compliant foam layer covered with a fabric overcoating. The cleaning station may also contain a detoning roll which contacts the cleaning roll to attract residual toner for disposal out of the station. There may be an electrical connection in the station to a biasing structure which will bias both the fabric overcoating and the detoning roll. The conductive fabric may have an average roughness (RA) not exceeding about 8 μm to 10 μm and the fabric comprises yarns of similar size to provide thereby a smooth and uniform surface texture.
