Abstract
A toner composition comprising a primary resin and at least one additional polymeric component is improved by reactive compatibilization of the additional polymeric component and the resin. For example, effective amounts of a functional secondary resin and a functional silicone oil having functionality reactive therewith are included and mixed by extrusion so as to reduce or eliminate speckling in printing with the toner and the improve toner powder flow.
