Abstract:
A method of making a toner composition includes preparing raw toner particles, increasing a surface area of the raw toner particles by contacting the raw toner particles with a base to produce base-treated raw toner particles, and mixing the base-treated raw toner particles with at least one surface additive such that the at least one surface additive attaches to a surface of the base-treated raw toner particles to obtain blended toner particles. A toner composition includes blended toner particles containing base-treated raw toner particles, and at least one surface additive attached to a surface of the base-treated raw toner particles, wherein a ratio of a triboelectric charge of the blended toner composition to a triboelectric charge of the base-treated raw toner particles is from about 0.8 to about 1.2.
