Abstract
A method for producing core shell toner for electrophotography according to one embodiment, includes surface treating the outer surface of a core shell toner particle with a alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons using a hydrolytic deposition process after the core shell toner particle is fully formed. This method results in the bonding of the alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons to the outer surface of the core shell toner particle. In an alternative method, the outer surface of the toner is surface treated with the alkoxysilane hydrocarbon solution and then fused to form toner particles. The alkoxysilane hydrocarbon surface treated core shell toner also can be mixed with magnetic carrier beads to form a developer mix to be used in a dual component development electrophotographic printer.
