Method for manufacturing toner

A method for manufacturing a toner composed of colored polymer particles (B) whose particle-size distribution is adjusted, comprising Step 1 for preparing colored polymer particles (A) that contain at least a binder resin and a colorant, and Step 2 for classifying said colored polymer particles (A), wherein said Step 2 is a step for performing classification by:

• (i) using a classifier that has a plurality of vane-wheel classifying rotors coaxially in a casing;
• enables the rotating speed of each classifying rotor to be set to be the same as or different from each other;
• and can simultaneously perform a plurality of stages of classification corresponding to each classifying rotor;
• and
• (ii) feeding a powder material comprising colored polymer particles (A), to which a fluidizing agent is added, to said classifier, wherein the average particle size of the fluidizing agent is smaller than the average particle size of the toner, and is 500 nm or less, the powder material is a material wherein 0.01 to 3 parts by weight of the fluidizing agent is added to 100 parts by weight of the colored polymer particles (A), and the fluidity index of the powder material to be classified is 10 or more;
• and further wherein the fluidizing agent added to the colored polymer particles (A) is practically completely removed in the Step 2 together with the fine-particle component of the colored polymer particles (A), thereby obtaining colored polymer particles (B), whose number content of fine particles of 3.17 μm or less is 3% or less.
