Abstract
An emulsion aggregation toner particularly adapted for use in hybrid scavengeless development includes toner particles of polymer binder, colorant and a surface additive package containing at least one additive negatively chargeable to a carrier and at least one additive positively chargeable to the carrier. The toner is able to exhibit high stable triboelectric charging ability, and substantially eliminates charge through and slow admix in a developer employing the toner.
