Process for preparing latex comprising charge control agent

A process comprising:

• forming, by emulsion polymerization, polymer resin particles in a latex, the polymer resin particles being formed from a mixture comprising:
• one or more monomer emulsions;
• and
• a non-surfactant-based charge control agent;
• wherein the emulsion polymerization is carried out under starved-fed conditions 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, wherein the toner particles are formed by emulsion aggregation/coalescence and wherein the toner particles support a sufficient triboelectric charge for use under A-zone environmental conditions in a single-component development system.
