    IPC: G03G9/08

    Abstract: 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.

    IPC: G03G9/08

    Abstract: An improved electrostatic printing method includes printing a first marking material, such as a fully colorized toner, and also printing a second marking material on the same area of the print substrate. The second marking material is a mixture of two toners, where at least one of the two toners has a lower color strength than the first marking material. The second marking material has the same hue as the first marking material, and the ratio of toners in the mixture is such that the second marking material has a color strength matching that of an undesirable optical density printing rage of the first marking material.
