PURPOSE:To provide a method for producing a fine toner narrow in particle diameter distribution, small in particle diameter and improved in chargeability and cleaning property. CONSTITUTION:After granulating a particle composed of at least a resin and a coloring agent in a wet system, the granulated material is aggregated and dried and by allowing the dried material to pass dispersedly into air flow which travels in the minimum space of 0.5-10mm formed between a rotor and a rotor or a stator and the rotor at a high speed, the amorphous toner particle having 1-20mum average particle diameter is obtained. |
