    摘要: The toner described herein contains toner particles containing polymer, colorant and cross-linked polymer. The cross-linked polymer is incorporated at least in the shell of the toner particles. Incorporating cross-linked polymer in the shell of the toner particles provide bumps in the surface of the toner particles. These bumps can behave as spacers. Such toner can be formed by aggregating at least polymer particles and colorant particles to form core particles; aggregating at least cross-linked polymer particles to the surface of the core particles; and coalescing the resulting particles to form toner particles.

    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.
