A toner composition that permits printing of clear-cut and high image quality without developing a fog or a blur is provided. Binder resin particles manufactured through a dispersing polymerization method are colored using a dye and are then subjected to a process of injecting an organic finely divided powder and a charge controlling agent and to a process of externally adding a hydrophobic silica and a conductive titanium oxide, thereby making a toner composition having an average particle diameter by volume of 7 mum or less, a coagulation level of 10% or less, and an external additive coating ratio of 70% or less
