Title: Cleaning device

Abstract: A device for cleaning electrostatic copier drums. A rotary bristle brush is positioned axis parallel to the drum and contacts the drum surface. The brush is received in a shroud which includes a toner collection sub-chamber having an orifice exit to a suction system to return toner from the sub-chamber to the toner reservoir. The orifice is localized, providing a high volume air flow at the orifice opening. Oscillatory means act within the sub-chamber to insure that all toner within the sub-chamber is presented to the orifice.
