Abstract
A toner composition having a high light transmission when printed on a transparent medium, in addition to being superior in strength and durability is provided. Binder resin particles manufactured through a dispersing polymerization method are colored using at least one kind of 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 a gel percentage of 2 to 15%.
Claims27
