Abstract
A photoreceptor cleaning brush for an electrostatographic imaging apparatus contains individual fibers provided with a finishing agent that is a water-miscible aliphatic organic compound containing a plurality of alcoholic hydroxy substituents. The finishing agent is selected from the group of compounds having a molecular weight of up to about 250 and polyethylene glycols having a number-average molecular weight of about 1000 to about 200,000. In an electrostatographic imaging apparatus, the photoconductive imaging element includes the described photoreceptor cleaning brush and a photoconductive surface portion that contains a polycarbonate binder resin. The cleaning brush removes toner from the photoconductive surface portion of the element without damaging it.
