Abstract
The toner includes emulsion aggregation toner particles having a core and a shell. The core includes binder including a first non-crosslinked styrene acrylate polymer and a crosslinked styrene acrylate polymer, at least one colorant, at least one wax, and aluminized silica. The shell includes a second non-crosslinked styrene acrylate polymer that is preferably the same as the non-crosslinked styrene acrylate polymer of the core. The aluminized silica is advantageously used as a coagulant in the emulsion aggregation formation of the toner. A developer containing the toner and a method of forming an image using the toner are also described.
