ABSTRACT:
The present invention relates to a non-magnetic monocomponent color toner and a preparing method thereof. In the non-magnetic monocomponent color toner including a toner mother particle, silica and titanium dioxide, the toner mother particle comprises a specific shaped particle size distribution of the charge control agents, and thus, providing non-magnetic monocomponent color toner with a narrow charge distribution and good chargeability. Accordingly, the color toner does not cause contamination in the non-imaging region. Also, because it has superior image density and printing efficiency and significantly improved charge maintenance, it has good long-term stability.
