Magnetic composite particles for magnetic color toner, magnetic color toner using the same, method for developing magnetic latent image using the toner, and method for developing electrostatic image using the toner

摘要

A magnetic color toner comprises a binder resin, a colorant and magnetic composite particles having an average particle diameter of 0.06 to 10.0 µm and comprising:magnetic core particles,a gluing agent coating layer which is provided on the surface of said magnetic particles, andan organic yellow-based pigment coat, an organic red-based pigment coat or an organic blue-based pigment coat which is provided on said gluing agent coating layer in an amount of from 1 to 200 parts by weight per 100 parts by weight of said magnetic core particles. The magnetic color toner exhibits not only a clear hue but also an excellent light resistance.
