ABSTRACT:
A process for the preparation of toner particles which comprises a suspension polymerization followed by a starved feed monomer addition process and wherein the suspension polymerization comprises the formation of an organic phase comprised of monomer, initiator, pigment and optional toner additives; adding the organic phase to an aqueous phase comprised of water and a stabilizer; shearing the resulting organic and aqueous phase mixture; polymerizing the monomer by heating to enable toner particles; and wherein said starved feed addition comprises adding a second monomer, optionally with crosslinking agents or initiators, and heating to polymerize the added monomer.
