Abstract
An apparatus for developing a latent image recorded on an imaging surface, including: a first developer unit for developing a portion of the latent image with a toner of custom color, the first developer unit including a housing defining a reservoir for storing a supply of developer material including conductive toner; a dispenser for dispensing toner of a first color and toner of a second color into the housing, the dispenser including device for mixing toner of the first color and toner of the second color together to form toner of the custom color; a donor member for transporting toner of the custom color on an outer surface of the donor member to a development zone; device for loading a toner layer of the custom color onto the outer surface of the donor member; and device for inductive charging the toner layer onto the outer surface of the donor member prior to the development zone to a predefine charge level; and a second developer unit for developing a remaining portion of the latent image with toner being substantial different than the toner of the custom color.
