Cleaning brush for electrostatographic imaging apparatus and apparatus containing same

摘要

A photoreceptor cleaning brush for use in an electrostatographic imaging apparatus comprises individual fibers provided with a finishing agent comprising 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. An improved electrostatographic imaging apparatus includes a photoconductive imaging element and a photoreceptor cleaning brush. The improvement comprises: the photoconductive imaging element having a photoconductive surface portion comprising a polycarbonate binder resin, and the cleaning brush comprising individual fibers provided with a finishing agent comprising 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. The cleaning brush removes toner from the photoconductive surface portion of the imaging element without damaging it.
