    摘要： A process for forming non-spherical toner particles by limited coalescence comprises: forming an organic phase comprising a polymeric material, a pigment, a quaternary ammonium tetraphenylborate salt, a phosphonium salt polymer formed by condensation of at least one dicarboxylic acid or dicarboxylic ester monomer with at least one diol monomer, at least one of the acid or ester monomers including a triarylphosphonium salt group, and a water-immiscible liquid; dispersing the organic phase in an aqueous phase containing a solid colloidal stabilizer; forming a suspension of small droplets of the organic phase in the aqueous phase by high shear agitation; removing the water-immiscible liquid from the small droplets, thereby forming a suspension of small solid particles in the aqueous phase; and separating and drying the solid particles, which are toner particles having a non-spherical shape.
