摘要:
A color toner comprising: a binder resin, and a colorant having an average particle diameter of from 0.005 to 0.30 µm, comprising:
extender pigments; a gluing agent-coating layer formed on surface of the extender pigment; and an organic pigment coat formed onto the gluing agent-coating layer in an amount of from 1 to 500 parts by weight based on 100 parts by weight of the extender pigments. The color toner exhibits not only a clear hue, but also excellent fluidity and dispersibility of colorants.
