ABSTRACT:
The present invention related to a toner for electrophotography comprising at least a binder resin, a coloring agent and a wax for off-set prevention, in which the wax is incompatible with the resin, dispersed insularly in the resin in the form of substantially spherical and/or substantially spindle-shaped particles, the number of spindle-shaped wax-particles occupying 70% or less of the total number of wax-particles. The spherical wax-particles have a following relationship between a mean wax-particle size (Dw) and a mean toner-particle size (Dt):
