Abstract
A toner suitable for use in electrophotography, etc., is composed of toner particles each containing a binder resin, a colorant and a wax component. Each toner particle has such a microtexture as to provide a cross section as observed through a transmission electron microscope (TEM) exhibiting a matrix of the binder resin, a particle of the wax enclosed with the matrix; and the binder resin dispersed in a particulate form in the wax particle, and the toner particles have a residual monomer content of at most 500 ppm by weight of the toner particles. The colorant may also be dispersed in the wax particle enclosed within the matrix of the binder resin.
