    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 method of making particles suitable for use as toners includes forming a mixture of sulfonated polyester resin, a colorant dispersion and optionally a wax dispersion, homogenizing the mixture, adding a coagulant to the mixture to aggregate the mixture to form aggregated particles, and coalescing the aggregated particles to form coalesced particles. In the method, when a predetermined average particle size is achieved during the aggregation and/or coalescing step, a complexing agent that complexes with ions of the coagulant is added in an amount effective to substantially halt any further particle growth. The complexing agent is believed to halt further growth by complexing with free coagulant ions still in the solution.
