Japanese Patent JP3397666
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a producing method of toner particles showing high transfer property and little changes in transfer property from the initial stage of use to after long-term use.
SOLUTION: In the production of toner particles containing a binder resin and a coloring agent, a device I described below is used. The device I is equipped with a first cylindrical treating room 29a, rotating axis 3 housed in the first cylindrical treating room, first rotor 2a having plural blades 9a on the front face.
