    摘要: A toner is disclosed that includes a toner binder of crystalline sulfonated polyester, wherein the crystalline sulfonated polyester is 90% by weight or more of the toner binder, and a colorant. In other embodiments, the toner includes a crystalline sulfonated polyester and a linear amorphous sulfonated polyester, and a colorant. In these embodiments, the crystalline sulfonated polyester is from about 20% to about 60% by weight of the toner binder and the linear amorphous sulfonated polyester is from about 40% to about 80% by weight of the toner binder. The toners possess excellent miniumum fixing temperatures in the range of from about 80° C. to about 130° C. Processes for preparing the toners are also described.
