<P>PROBLEM TO BE SOLVED: To provide resin particles having sufficiently narrow particle size distribution obtainable by using a liquid or supercritical fluid, and to provide a method for producing the resin particles having the sufficiently narrow particle size distribution by using a liquid or supercritical fluid. <P>SOLUTION: There is provided a resin particle (C) having a microparticle (A) fixed to or formed as a film on the surface of a resin particle (B) containing a resin (b), wherein the swelling degree of the microparticle (A) by liquid or supercritical carbon dioxide (X) at a temperature lower than the glass transition temperature or the melting point of the microparticle (A) is 16% or less, and a crystalline resin (a1) having a specified composition is used as the microparticle (A). <P>COPYRIGHT: (C)2013,JPO&INPIT |
