Abstract:
An apparatus for delivering electrostatically charged toner particles to an image receiving member, including:a traveling electrostatic wave toner conveyor overlaid with longitudinal barriers, said longitudinal barriers dividing said toner conveyor into parallel columns and the combination of said traveling electrostatic wave toner conveyor and said longitudinal barriers forming isolated potential wells to receive pixel packets of toner therein, wherein said traveling electrostatic wave toner conveyor conveys said pixel packets, in an aerosol state, to said image receiving member; an ejector electrode in registry with each of said columns, said ejector electrodes responsive to modulated voltage applied thereto, to modulate the quantity of toner in said pixel packets in said columns; and focusing means to transfer said pixel packets from said toner conveyor to said image receiving member.
