摘要： A toner of a sulfonated polyester resin and at least one colorant is made to contain from about 0.01% by weigh to about 3% by weight of dry toner in total of lithium, sodium, zinc and calcium. The sulfonated polyester resin may be an alkali metal sulfonated polyester resin, wherein the alkali metal may be sodium and/or lithium. The toner may be formed in an emulsion aggregation process in which an alkali (II) metal salt such as a zinc salt and/or a calcium salt is used as an aggregating agent.

摘要： A process for preparing toner particles and compositions adapted for use in preparing toners that comprise a blend of a first polyester resin with a second sharp melting polyester resin. The process includes forming an emulsion resin comprising a branched polyester resin, a crystalline polyester resin, a colorant, and optionally a wax. The resin mixture is aggregated using an aggregating agent, such as a zinc acetate solution, to form an aggregate mixture. The aggregate mixture is then coalesced at a temperature of from about 5 to about 20° C. above the Tg of the emulsion resin to produce the resultant toner particles.

摘要： A toner having an amorphous resin, a crystalline resin, and a colorant, wherein the crystalline resin has a melting temperature of at least 70° C. and a recrystallization point of at least 47° C. exhibits improved document offset properties and improved heat cohesion. Annealing the toner further improves the heat cohesion and morphology of the toner.
