EMULSION AGGREGATION POLYESTER TONERS

摘要

An emulsion aggregation toner including an amorphous resin and a crystallin e resin, wherein the toner has an acid value of from about 16 mg/eq. KOH to about 40 mg/eq. KOH and a relative humidity sensitivity ratio of from about 1 to abou t 2, and wherein the crystalline resin has a melting point of at least about 60.degree.C. The process for forming particles including generating an emulsion of a polyester resin having an acid value of from about 16 mg/eq. KOH to about 40 mg/eq. KOH and generating aggregate particles from the emulsion. Increased charge maintainability and resistivity of the toner result, thereby generating high print quality and high gloss, a nd provide stable xerographic charging in all ambient environments.
