Cleaning Brushes that Prevent Clear Film Streaking

Clear film streaking appears to manifest itself under some conditions when using the presently implemented pure polytetrafluoroethylene fiber brushes, for cleaning the electrophotographic organic photoconductor. (OpC).

The clear film streaking problem can be minimized and in some instances overcome by the use of a brush 11, which is comprised of approximately equal parts antistatic nylon fibers and polytetrafluoroethylene fibers. The exact percentage of blend may be varied to optimize results. The fibers are substantially uniformly distributed throughout the fibrous portion 13 of the brush material and are uniformly intermingled with each other. This prevents the presentation of areas substantially all polytetrafluoroethylene fibers or all nylon fibers to the surface of the OPC. Other fibers that may be substituted include rayon, DACRON*. and DYNEL**. * Trademark of E. I. du Pont de Nemours & Co. ** Trademark of Union Carbide Corporation.
