摘要:
A cleaning brush for use in an electrostatographic imaging apparatus, including a plurality of individual electrically conductive fibers secured to a brush core and having fiber tips relatively remote from the brush core, wherein the cleaning brush includes an electrically conductive plane at a surface of the brush core, or between a surface of the brush core and the electrically conductive fibers, effective for inducing an electrical potential to the conductive fibers when an electrical potential is applied to the electrically conductive plane, and at least one of a relatively non-conductive layer electrically insulating the conductive plane from the conductive fibers, or electrically insulating coatings on tips of the electrically conductive fibers remote from the brush core. The insulative, or non-conductive, layer between the fibers and the conductive plane of the brush prevent excessive current draw.
