Abstract
A process includes dissolving a polyester resin in a mixture of a single organic solvent, a base and water to form a resin mixture; neutralizing the resin mixture with a neutralizing agent to provide a neutralized resin mixture; adding water to the neutralized resin mixture until phase inversion occurs to form a toner resin emulsion; removing the single solvent to form a polyester latex.
