摘要： A toner producing system which can efficiently produce toner having a sharp particle size distribution by suppressing the occurrence of microscopic powders and improve energy efficiency in pulverization. The system is furnished with a second pulverizing apparatus having a second colliding plate inclined at an angle in a range between 45.degree. and 90.degree. inclusive with respect to a direction in which a raw material subject to pulverization is introduced into a second pulverizing chamber through a second nozzle, and a third pulverizing apparatus having a third colliding plate with a conical member being placed thereon, so that the raw material introduced into a third pulverizing chamber through a third nozzle collides with an inner surface thereof following the collision with the third colliding plate.

摘要： The extra-fine toner arising in the toner producing process, is returned to the mixing step where it is mixed again with the binder resin and the coloring agent, and the compound is sent out to the kneading step. In this procedure, the particle size of the binder resin is set in accordance with the particle size and blending amount of the extra-fine toner, the kind of the binder resin, etc. By using the binder resin having the thus determined particle size, the amount of the binder to be fed into the mixer or the amount of the compound ejected from the mixer are maintained uniform. Further, when the extra-fine toner is mixed with the starting materials, the blending ratio of the extra-fine toner to the starting material is set between 5 wt. % and 10 wt. %, and the blending ratios of the charge control agent and the coloring agent are set equal to those of the normal process where no recycled toner is added.
