Provided is an apparatus for heat treatment capable of heat-treating toner particles efficiently and uniformly while suppressing increase of coarse particles due to coalescence, to thereby enable stable toner production. The apparatus for heat-treating powder particles each of which contains a binder resin and a colorant includes: a cylindrical treatment chamber in which the powder particles are heat-treated; a columnar member (6) provided so as to protrude from a lower end part of the treatment chamber toward an upper end part thereof; a powder particle supply unit (2) for supplying the powder particles to the treatment chamber; a hot air supply unit (3) for heat-treating the supplied powder particles; and a collection unit (5) for collecting the heat-treated powder particles discharged outside the treatment chamber through a toner discharge port provided on the lower end part side of the treatment chamber. The hot air supply unit is provided so that the hot air is supplied along an inner circumferential surface of the treatment chamber. The powder particle supply unit includes multiple particle supply ports provided on an outer circumferential surface of the columnar member. The toner discharge port is provided in an outer circumferential portion of the treatment chamber so as to keep a rotation direction of the powder particles.
