A toner composition including a binder, colorant, and a toner particle surface additive component comprised of a mixture of first coated fumed silica coated with an alkylsilane compound and a second coated fumed silica coated with an aminoalkylsilane compound wherein the first and second fumed silicas each has the same relatively large particle size. A toner composition including a binder, colorant, and a mixture of two distinct coated fumed silicas as surface additives wherein one silica is surface coated with an alkylsilane compound and the other silica is surface coated with an aminoalkylsilane compound and where the silica used for the alkylsilane coating is larger in size diameter than the silica used for the aminoalkylsilane coating. |
