Abstract:
1. A method for producing resinous particles, comprising: melting a mixture comprising a binder resin and at least one additive having a melting point which is lower than T1/2 of the binder resin, so as to prepare a molten material, where T1/2 denotes a softening point determined in accordance with a 1/2 method; atomizing resinous particles from the molten material in an atmosphere having a temperature which is higher than a glass transition temperature of the binder resin and is lower than 3 times of T1/2 of the binder resin; retaining the resinous particles in an atmosphere having a temperature which is higher than the glass transition temperature of the binder resin, and is lower than 1.5 times of T1/2 of the binder resin for 1 second to 15 seconds; and cooling and solidifying the resinous particles.
