Abstract
A combination cleaning and surface renewing apparatus includes a cleaning member for removing residual particles from the image-bearing surface of electrostatographic reproduction apparatus. The combination apparatus also includes a first abrading member mounted downstream of the cleaning member for removing at least an atomic layer of material forming the image-bearing surface. The first abrading member is impregnated with abrasive aluminum oxide particles. The combination apparatus also includes a second abrading member mounted downstream of the first abrading member for polishing and renewing the abraded image-bearing surface. The second abrading member includes particles of colorless toner particles chemically bonded therein.
