Abstract (en)
[origin: EP0605169A1] Disclosed herein is a method for producing a toner for electrostatic development, comprising crushing a toner material obtained by melting, kneading and cooling starting toner materials comprising at least a resin and a colorant, and then pulverizing the crushed toner material by an impact pulverizer having a pulverizing section formed by disposing a stator having ridges of a triangular waveform at an inner surface thereof and a rotor having ridges of a triangular waveform at an outer surface thereof at a gap between the ridges of the stator and of the rotor. <IMAGE>
