ABSTRACT:
A method and apparatus for cleaning toner and/or other contaminant particles from a moving surface to be cleaned in an electrostatographic apparatus includes a cleaning blade, such as a wiper blade or a scraper blade, that engages the surface to be cleaned at a first location to remove the particles from the surface. A dust seal blade is provided that extends toward the surface in a second direction generally opposite to the first direction, which corresponds to the direction of motion of the surface to be cleaned, and is of a length and supported so as to be able to contact the surface to be cleaned at a second location upstream of the first location. The cleaning blade, the dust seal blade and the surface to be cleaned form a cavity for containing contaminant particles to assist in operation of the cleaning blade apparatus.
