LIQUID ELECTROPHOTOGRAPHIC TONER ABSTRACT OF DISCLOSURE Liquid toners for developing electrophotographic images contain dispersed toner particles which are based on a polymer with multiple characteristics. These particles comprise a thermoplastic resinous core with a Tg below room temperature which is chemically anchored to an amphipathic copolymer steric stabilizer containing covalently attached groups of organic acid containing moieties having pKa's less than 4.5 which in turn are chemically bonded to metal soap containing compounds derived from organic acids having a pKa greater than 4.5. The toner particles so formed have advantageous properties of high charge/mass, and good charge and dispersion stability.
