ABSTRACT:
The present invention relates to a method for manufacturing a toner with adjusted particle size distribution having a step of preparing colored particles that contain a binder resin and a colorant, and a step of classifying the colored particles. In the classification step, 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 is used; and the powder material comprising colored particles to which a fluidizing agent is added is fed to the classifier to perform classification.
