    • An emulsion aggregation toner including an amorphous resin and a crystalline 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 about 2, and wherein the crystalline resin has a melting point of at least about 60° 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, and provide stable xerographic charging in all ambient environments.
    • 包含无定形树脂和结晶树脂的乳液聚集调色剂,其中调色剂具有约16mg / eq的酸值。 KOH至约40mg / eq。 KOH,相对湿度敏感性比为约1至约2,并且其中所述结晶树脂具有至少约60℃的熔点。用于形成颗粒的方法包括产生具有酸值为 约16mg / eq。 KOH至约40mg / eq。 KOH并从乳液中产生骨料颗粒。 增加调色剂的电荷维持性和电阻率,从而产生高打印质量和高光泽度,并在所有环境环境中提供稳定的静电放电。
