Disclosed are core-shell resin particles (C2) each comprising one or more film-like shell layers (P) comprising a resin (a) which is a polyurethane resin and a core layer (Q) comprising a resin (b). A core-shell resin particle (C2) is characterized in that the weight ratio between (P) and (Q) is from 0.1:99.9 to 70:30, the volatile content in the resin particle (C2) is not more than 2 weight %, and the content of vinyl resins in the resin (b) is not more than 30 weight %. Such resin particles have a uniform particle diameter and are excellent in electrostatic properties, thermal and storage stability and thermal characteristics.
