Microsuspension processes for toner compositions

A process for the preparation of toner compositions consisting essentially of dissolving a polymer, in an organic solvent;

• dispersing the resulting solution in an aqueous media containing nonionic surfactant;
• stirring the mixture with heating to remove the organic solvent thereby obtaining suspended particles of about 0.05 micron to about 2 microns in volume diameter;
• subsequently homogenizing the resulting suspension with a pigment in water and nonionic surfactant;
• followed by aggregating the suspension by heating thereby providing toner particles with an average particle volume diameter of from between about 3 to about 21 microns.
