Process for producing toner

A process for producing a toner, comprising, in sequence, the steps of:

• (A) dry-mixing for not longer than 120 minutes at least colorant particles and binder resin particles, said binder resin particles having a weight average particle diameter from 140 .mu.m to 300 .mu.m, while applying thereto, shear, compression and impact forces, to
• (i) disperse the colorant particles and the binder resin particles to fasten the colorant particles to the binder resin particles, and to
• (ii) obtain a mixture comprising at least the colorant particles fastened to the binder resin particles wherein the weight average particle diameter of the mixture is from 10.7% to 25.7% less than the weight average particle diameter of the binder resin particles prior to said dry-mixing step (A);
• wherein the shear, compression and impact forces are applied
• (a) by the movement of ball media having a diameter from 1 mm to 15 mm in a main body container caused by a rotating agitator arm present in the main body container, or
• (b) by passing the colorant particles and the binder resin particles through a clearance of 0.5 mm to 10 mm between a rotor blade and a stator fixed around the rotor blade;
• (B) melt-kneading the mixture;
• (C) cooling the resulting kneaded product to solidify;
• and
• (D) dry pulverizing the cooled product to form the toner.
