ABSTRACT:
A cylindrical fiber brush useful in electrostatic charging and cleaning in an electrostatographic imaging process comprises an elongated cylindrical core having bound thereto a spirally wound conductive pile fabric strip forming a spiral seam between adjacent windings of the fabric strip, the fiber fill density of said fabric strip at the strip edge being at least double the fiber fill density in the center portion of the fabric strip. The increased fiber fill density at the strip edges provides additional fibers to fill the seams between the adjacent windings and improves the charging and cleaning performance at low rotational speeds.
