1. A method of attaching one or more additives to a toner particle surface comprising:
conducting a carrier gas comprising toner particles into a reaction tube which is in communication with a microwave resonant cavity, wherein said microwave resonant cavity is in microwave with a wave guide; conducting plasma-inducing microwaves in said wave guide to said cavity; generating carrier gas plasma in said reaction tube in said microwave resonant cavity, wherein said toner particles are exposed to said carrier gas plasma; igniting said exposed plasma, wherein said ignited plasma activates toner particle surfaces; exposing said activated toner particles to a powder cloud comprising one or more additives, wherein said one or more additives attach to the surface of the activated toner particles; and exposing said toner particles comprising additives to an elevated temperature to produce toner particles comprising additives at the surface thereof. |
