Abstract
A process includes forming, by emulsion polymerization, polymer resin particles in a latex, the polymer resin particles being formed from a mixture including one or more monomer emulsions and a non-surfactant-based charge control agent, the emulsion polymerization is carried out with a solids content in a range from about 10 to about 30 percent by weight of the mixture, and forming toner particles from the polymer resin particles, the toner particles support a sufficient triboelectric charge for use under A-zone environmental conditions in a single-component development system.
