摘要： A developer mix used in a dual component development (DCD) system is a mixture of toner particles and magnetic carrier particles, wherein the magnetic carrier particle is surface treated with a hydrophobized titania particle. The surface treatment with a hydrophobized titania particle may be selected from either a spherical, disk, or spindle shaped. Tribocharge of the toner and the toner charge stability across cartridge life or environments may be suitably modified by selecting a preferred size and shape of the hydrophobized titania.

摘要： A color toner image with a metallic effect can be prepared by forming one or more latent images and developing them with non-conductive metallic dry toner particles and color toner particles. The developed color toner image can be transferred to a receiver material, and fixed to provide a color toner image with a metallic effect. The non-conductive metallic dry toner particles have a polymeric binder phase and non-conductive metal oxide particles dispersed therein. Before fixing, each non-conductive metallic dry toner particle has a mean volume weighted diameter (Dvol) of 15-40 μm and the non-conductive metal oxide particles are present in an amount of at least 20-50 weight %. The ratio of the non-conductive metallic dry toner particle Dvol to the average equivalent circular diameter (ECD) of the non-conductive metal oxide particles in the non-conductive metallic dry toner particles is greater than 0.1 and up to and including 10.
