Abstract:
1. A process comprising: contacting at least one amorphous resin with at least one crystalline resin in an emulsion to form small particles, wherein the emulsion includes an optional colorant, an optional surfactant, and an optional wax; aggregating the small particles to form a plurality of larger aggregates; passing at least one charge control agent in a dispersion through a high energy disperser at a pressure of from about 3,000 pounds per square inch to about 30,000 pounds per square inch to form a first charge control dispersion; combining the first charge control dispersion with an emulsion or dispersion possessing at least one resin to form a second charge control dispersion; contacting the larger aggregates with the second charge control dispersion to form a resin coating thereon; coalescing the larger aggregates to form toner particles; and recovering the toner particles.
