The present invention relates to a high-resolution toner produced by increasing the charge density by selectively placing the charge control agent on the surface in combination with a polar grafting agent by suspension polymerization. When synthesizing the toner core, a polar grafting agent is included in the monomer, and a reactor containing a polar group is introduced to the surface, and a charge control agent is added to the core or shell to form the charge toner surface by the interaction of the polar grafting agent and the charge control agent. Selectively located at to increase the surface charge density, which has the effect of achieving a high resolution. |
