    摘要: Disclosed is a resin particle having excellent low-temperature fusibility, having a sufficiently narrow size distribution, and that is obtained using a liquid or supercritical fluid. In the resin particle (C), which comprises a microparticle (A) containing a resin (a) being coated to or adhered to the surface of a resin particle (B) that contains another resin (b), the degree of swelling of the microparticle (A) resulting from liquid or supercritical carbon dioxide (X) at a temperature less than the glass transition temperature or the melting point of the microparticle (A) is no greater than 16%, and with the resin (a) as a constituent unit, the resin particle (C) contains 0.1-50 wt% of a non-crystalline non-halogen vinyl monomer (m1) of which the solubility parameter (SP value: (cal/cm 3 ) 1/2 ) is 7-9.
