Abstract
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.
