ABSTRACT:
The present disclosure relates to a process for producing a toner particulate composition from aqueous dispersions containing aggregates of a polymer binder and other toner ingredients. An ionic surfactant may be used to form the dispersion along with an ionic polymer flocculent wherein the ionic polymer flocculent undergoes a molecular conformational change, which may be triggered by pH adjustment, leading to flocculation and particle growth.
