    摘要: A dual coagulant toner process comprising adding a first component comprising an ionic salt to a latex emulsion of resin having a colorant mixed therein, to form a latex emulsion; adding a second component comprising an organo-metallic aggregating agent to the latex emulsion by agitation at a temperature above a glass transition temperature of the resin, thereby forming a product mixture; subsequently cooling the product mixture to a temperature below the glass transition temperature of the resin, in order to form toner particles; and optionally, isolating the toner particles.

    摘要: Toner particles, preferably emulsion aggregation toner particles, have improved relative humidity sensitivity through inclusion therein of silicate clay particles such as kaolin clay. The toner particles include a binder, preferably an acrylate-containing binder, at least one colorant, and silicate clay particles distributed in the binder. In a core-shell embodiment, the silicate particles are distributed in the core, the shell layer, or both. Developers of the toner in combination with carrier particles are also described.
