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, said donor member includes an electrode array on the outer surface thereof, said array including a plurality of spaced apart electrodes extending substantial across width of the surface of the donor member; first and second discrete vibrating members in contact with said donor member, for applying first and second discrete high frequency vibratory energy to said donor member; a multi-phase voltage source operatively coupled to said electrode array and said vibrating members, wherein the phase of said multi-phase voltage source being shifted with respect to each other such as to create an electrodynamic wave pattern for moving toner particles along said electrode array and driving said vibrating members.
