Abstract

Disclosed is a non-contact cleaning apparatus for use in, for example, electrostatographic printing machines, comprising an acoustic assist device which is situated behind a belted photoreceptor and which assist device vibrates to liberate charged toner from the surface of the photoreceptor. The liberated toner is airborne and subsequently captured by an electrically biased receiver roller spaced a small distance above the photoreceptor surface. The captured toner is continuously removed fkom the biased roller with conventional means, for example, a scraper blade. The apparatus can be used alone or in conjunction with other cleaning systems.
