A plastisol is defined as a thermoplastic binder dispersion prepared by dispersing polymer particles in a liquid medium in which the polymer is insoluble. Plastisol based electrophotographic toners have been prepared with a novel composition that exhibits increased dispersion stability and improved chargeability. The plastisol based electrophotographic toners contain either a combination of acid functional binder resin plus base functional dispersant or base functional binder plus acid functional polymeric dispersant.
