Abstract
An apparatus for manufacturing toner is provided which includes a pulverizer for pulverizing a material into particles, a classifier for classifying the particles by size, a discharging path for discharging the particles from the pulverizer to the classifier, a returning path for returning relatively coarse particles among the classified particles from the classifier to the pulverizer, and a handling unit for handling particles. A method for manufacturing toner is also provided which includes pulverizing a material into particles in a pulverizer, discharging the particles from the pulverizer to a classifier via a discharging path, classifying the particles by size in the classifier, and returning relatively coarse particles among the classified particles from the classifier to the pulverizer. The handling unit is provided on at least one of the discharging path and the returning path, and includes a mechanism for preventing accumulation of the particles using airflow.
