A production process of a toner, wherein wet colored resin particles are poured into a rotary vane type agitating device having a structure that an agitating vane fixed to a rotating drive shaft extending through a bottom wall of an agitation vessel is arranged at a bottom of the agitation vessel, and at least one gas inlet port and at least one gas outlet port are arranged at a lower portion of the agitation vessel and an upper portion of the agitation vessel, respectively, the wet colored resin particles are dried by a method, in which the wet colored resin particles are agitated by the rotary vane within the agitation vessel while supplying a heated gas, thereby forming a fluidized bed, and a mixed gas containing water is discharged from the gas outlet port to the outside, and at that time, drying conditions are controlled in such a manner that the temperature of the gas discharged falls within a range from 20 to 60° C.
