An electrographic toner can include toner particles having a multi-particulate additive disposed on an exterior surface of the toner particles. The toner particles can have a specific surface area from 3.0 m.sup.2/g to 3.65 m.sup.2/g and can include a binder resin, a colorant, and a releasing compound. The multi-particulate additive can include aluminum oxide particles, small sol-gel silica particles having a particle size distribution from 20 nm to 50 nm, large sol-gel silica particles having a particle size distribution from 90 nm to 130 nm, and fumed silica particles surface-treated with polydimethylsiloxane (PDMS).
