ABSTRACT:
A toner composition and a method of preparing toner particles using the toner composition. The toner composition comprises a monomer for a binding resin, a coloring agent, a stabilizer, a charge controller, a lubricant and a polymerization initiator, wherein the stabilizer is obtained by dispersing hydrophobic silica into distilled water of pH 10.about.14, and then adjusting pH of the dispersion into 6.about.8. The toner particles prepared from the toner composition have improved in charge quantity, average particle diameter and distribution in particle diameter. Particularly, when the toner composition contains a surfactant, dispersion property of the color agent and the charge controller can be improved, thereby resulting in a better image quantity.
