Blended toners of functional color

Abstract

This invention is directed to a developer composition comprised of a resin, a colorant such as cyan, magenta, yellow, or mixtures thereof, and a single carrier. In one embodiment there is combined with a single carrier material, such as a steel carrier or a nickel berry carrier, a cyan toner, such as a styrene/n-butyl methacrylate resin, and copper tetra-4-(octadecylsulfonomido) phthalocyanine, a magenta toner material comprised of styrene/n-butyl methacrylate copolymer resin and 2,9-dimethyl substituted quinacridone, and/or a yellow toner material comprised of styrene/n-butylmethacrylate copolymer resin and a diaryldide yellow 3,3-dichlorobenzidene aceto acetanilide. The developer composition is useful for developing color images in an electrophotographic imaging system. In this system a photoreceptor material contained therein is charged, imagewise exposed, followed by development, transfer of the developed image to a suitable substrate such as paper, and permanently fixing the developed image, by heat for example, to the substrate.
