Abstract:
An apparatus for developing a latent image recorded on an imaging surface, comprising:a housing defining a chamber for storing a supply of developer material comprising toner;a dispensing system for dispensing toner of a first color and toner of a second color into said housing;an air system for fluidizing and mixing toner of said first color and toner of said second color;a donor member, spaced from the imaging surface, for transporting toner on an outer surface of said donor member 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; 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 for moving toner particles to and from a development zone.
