Abstract
Toner particles and toner compositions may be formed using a charge control agent that promotes positive triboelectric chargeability. Toner compositions may comprise: a plurality of toner particles comprising an anionic polymer, the toner particles comprising a core surrounded by a shell, and at least one charge control agent localized within the shell of the toner particles, the at least one charge control agent being positively chargeable.
