Abstract

Toner particles and toner compositions may be formed using a charge control agent that promotes positive triboelectric chargeability. Toner compositions may comprise: toner particles comprising a polymer bearing a plurality of negatively charged functional groups and at least one charge control agent blended within the polymer. The at least one charge control agent comprises a cationic portion and an anionic portion, and the cationic portion forms an ionic association with at least a portion of the negatively charged functional groups to reduce an overall negative charge of the polymer. The at least one charge control agent is present in at least one location within the toner particles. The toner particles and toner compositions may exhibit positive triboelectric chargeability.
