Abstract
The present disclosure relates to chemically processed toner that makes use of aqueous dispersions of release agent and/or pigment and solutions of a polymeric resin binder. The polymer solution may be prepared in an organic solvent wherein the organic solvent has some level of solubility in water. The polymer solution may then be combined with an aqueous dispersion of pigment and/or release agent which dispersions may include an aqueous polyelectrolyte and/or an aqueous dispersion of colloidal particles. This may be followed by agglomerating and forming particles of toner of a desired number and/or volume average particle size and/or degree of circularity.
