摘要: Toner including toner particles having a calcium-containing material at least in a surface portion of the toner particle, wherein the toner particles contain calcium in an amount of from 20 ppm to about 300 ppm of calcium by dry weight of the toner. Developer including a carrier and a toner, wherein the toner includes toner particles having a calcium-containing material at least in a surface portion of the toner particles. In an emulsion aggregation process for making toner particles, the toner particles are treated with calcium. The addition of calcium to the toner particles improves toner performance by lowering cohesion and charging, thereby generating an image of high gloss.

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.
