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 including toner;a donor member, spaced from the imaging surface, for transporting developer material on the surface thereof to a region opposed from the imaging surface;means for loading developer material onto a grid;said grid, spaced from in between said donor member and said loading means; said grid having electrode arrays on the outer surface thereof, said arrays including a plurality of spaced apart electrodes extending across substantial width of the surface of the grid, said grid comprises a closed loop; anda multi-phase voltage source operatively coupled to said electrode arrays, the phase being shifted with respect to each other such as to create traveling electrodynamic wave patterns for moving toners along the surface of said electrode array and with bias voltages for moving toners between said loading means, said grid and said donor member.
