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.

Abstract: A chemically prepared toner composition according to one example embodiment includes a core including a first polymer binder, a colorant and a release agent; a shell that is formed around the core that includes a second polymer binder; and a borax coupling agent between the core and the shell and an alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons that are bonded to the outer surface of the shell using a hydrolytic deposition process. This successful alkoxysilane hydrocarbon surface treatment on the outer surface of the toner particle results in attaining a desirable charge stability in hot and humid environments and ultimately improving the quality of the toner, especially by reducing toner dusting, toner fuming and ultra-fine particles generation.
