    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.

    摘要: Disclosed is a migration imaging member which comprises (a) a substrate, (b) a conductive layer comprising indium tin oxide dispersed in a polymeric binder, (c) a siloxane film charge blocking layer comprising a hydrolysis reaction product of a silane of the formula ##STR1## wherein R.sub.1 is an alkylidene group, R.sub.2 and R.sub.3 are each, independent of the other, a hydrogen atom, an alkyl group, a phenyl group, or a poly(ethyleneamino) group, and R.sub.4, R.sub.5, and R.sub.6 are each, independent of the others, alkyl groups, said siloxane having reactive hydroxyl and ammonium groups attached to silicon atoms, and (d) a softenable layer comprising a softenable material and a photosensitive migration marking material. Optionally an antistatic layer comprising indium tin oxide dispersed in a polymeric binder is situated on the surface of the substrate spaced from the softenable layer.
