Abstract
An apparatus for removing electrostatically charged particles from a surface such as the backside of an image bearing belt of the type found in an electrostatographic printing apparatus or a drive roller supporting an image bearing belt. The apparatus includes an electrically biased foam pad having a conductive substrate and conductive foam material extending outwardly therefrom to contact the surface to be cleaned, a supporting device, and a cleaning device for removing collected particles from the foam pad. The supporting device for the foam pad rotates, thereby causing clean foam material to contact the surface to be cleaned.
