PROBLEM TO BE SOLVED: To provide a styrene acrylate emulsion aggregation toner capable of achieving excellent print quality with specially controlled gloss properties. SOLUTION: 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 process of the toner. COPYRIGHT: (C)2007,JPO&INPIT
