Abstract:
An apparatus for developing a latent image recorded on an imaging surface, comprising:a housing defining a chamber storing a supply of developer material;a donor member, spaced from the imaging surface, for transporting developer material 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 electrode array including a plurality of spaced apart electrodes extending substantially across the width of the surface of the donor member;means for loading developer material onto said donor member, said loading means includes a cascade loading member, spaced from said donor member, for cascading developer material onto said donor member at a predefined velocity; anda multi-phase voltage source operatively coupled to said electrode array, the phase being shifted with respect to each other such as to create an electrodynamic wave pattern having a phase velocity for moving developer material to and from a development zone.
