摘要：
The present invention relates to a toner having a double- or triple-layered structure. The present invention is effective in that pigments and charge control agents are located most properly for the realization of high-resolution toners through addition and polymerization of hydrophilic monomers or polymers with the toners; the manufacture of high-resolution toners becomes very easy irrespective to the kind and amount of a wax used for polymerized toners by forming thin layers by using polar grafting agents; and long-term preservation is assured as well as the affect by moisture is minimized.
