As examples of specific components of the developer composition involved, there can be utilized with the charge enhancing additive a styrene/n-butyl methacrylate resin, a carbon black colorant, and a steel core carrier coated with a vinylidene fluoride polymer. These materials are useful for developing images in xerographic systems wherein the photoreceptor is charged negatively.
