Abstract
An electrostatographic imaging apparatus and method for cleaning remnant toner. An intermediate transfer member (ITM) is in transfer relation to a primary image-forming member to transfer the toner image from the primary image-forming member to the ITM. The ITM then transfers the image to a receiver sheet. A cleaning brush including plural individual brush fibers in engagement with the ITM removes residual toner from the ITM. The fibers each include an electrically conductive core and a surrounding substantially nonconductive annular portion. An electrically conductive backing secures the fibers and is adapted to electrically induce a potential from the backing to the cores of the fibers. The backing is substantially electrically insulated from the electrically conductive cores of the fibers. An electrical potential is established on the backing which is induced upon the cores of the fibers to attract remnant toner from the ITM to the brush. A detoning member includes an electrically conductive surface that contacts the brush fibers.
