HEAT TREATING APPARATUS FOR POWDER PARTICLES AND METHOD OF PRODUCING TONER

摘要

A production apparatus that does not generate coalesced particles and can reduce a generation frequency of a product having a high circularity by a uniform treatment even if the throughput is increased is provided. A heat treating apparatus for powder particles containing a binder resin and a colorant, the heat treating apparatus including: a treating chamber 6 in which a heat treatment of the powder particles is performed; a raw material-supplying unit for supplying the powder particles to the treating chamber; a hot air-supplying unit 7 that supplies hot air to the treating chamber; a cold air-supplying unit 8 that supplies cold air for cooling the heat-treated powder particles; and a recovering unit 10 that recovers the heat-treated powder particles; wherein the raw material-supplying unit includes an introducing tube 3 and a distributing member, and the distributing member is provided with a protruding member 4 on a portion opposite to an outlet portion of the introducing tube, and the distributing member includes a supplying tube 5 including two or more flow paths that extend radially outwardly from the protruding member to a wall surface of the treating chamber.
