Abstract
An apparatus for developing a latent image recorded on an imaging surface, including: a housing defining a chamber for storing a supply of developer material comprising toner; a donor member, spaced from the imaging surface, for transporting toner on the surface thereof to a region opposed from the imaging surface, the donor member includes an electrode array on the outer surface thereof, the array including a plurality of spaced apart electrodes extending substantial across width of the surface of the donor member; and a multi-phase voltage source operatively coupled to the electrode array, for generating a first electrodynamic wave pattern for moving toner particles along the surface of the electrode array to and from a development zone and generating a second electrodynamic wave to provide a fast oscillating-like toner motion along and perpendicular to the surface of the electrode array.
