ABSTRACT:
In an electrostatographic reproduction apparatus wherein a latent image charge pattern is formed on a moving dielectric member web and developed with pigmented marking particles to form a transferable developed image on the dielectric member web, an improved cleaning assembly for removing residual marking particles and debris from the dielectric member web. The improved cleaning assembly comprises a cleaning brush supported in a housing. The housing is located to position the peripheral surface of the cleaning brush in cleaning engagement with the dielectric member web, and a vacuum is established within the housing. A relatively stiff cleaning blade is supported in engagement with the dielectric member web at a predetermined positional orientation under a sufficient loading so as to cause the dielectric member web to be substantially deflected by the blade.
