ABSTRACT:
The present invention relates to a non-magnetic monocomponent color toner composition and a method for preparing the same, and more particularly to a non-magnetic monocomponent color toner composition having a narrow charge distribution, good charging characteristics, good environmental independence, superior image characteristics, high transfer efficiency and long-term stability caused by significantly improved charge maintenance capability, and a method for preparing the same. The non-magnetic monocomponent color toner composition of the present invention is prepared by coating organic particles having an average particle size of 0.3 to 2.0 μm, organic particles having an average particle size of 0.05 to 0.25 μm, and silica on toner mother particles.
