METHOD FOR SHAPING TONER PARTICLE INTO SPHERICAL SHAPE AND DEVICE FOR SHAPING TONER PARTICLE INTO SPHERICAL SHAPE

摘要

PROBLEM TO BE SOLVED: To provide a method for shaping toner particles into spherical shape by which toner particles can be formed into spherical shape by atmospheric plasma at a low running cost while preventing toner particles having melted surfaces from aggregating, and spheric toner particles can be mass-produced, and to provide a device for shaping toner particles into spheres.;SOLUTION: A plasma generating means to generate a plasma environment at the atmospheric pressure and a toner supply means to continuously supply toner particles T in a gas phase are held in a first cylindrical section 2. A second cylindrical section 6 which is detachably attached to the first cylindrical section 2 is provided with a cooling gas supply means to supply a cooling gas to rapidly cool the toner particles which are continuously supplied to the plasma environment and shaped into spherical shape by surface melting.;COPYRIGHT: (C)2007,JPO&INPIT
