An object of the present invention is to obtain resin particles having a sharp particle size distribution, excellent low-temperature fixability, and excellent heat-resistant storage stability. A resin fine particle comprising a crystalline resin (a) having a crystallinity of 20 to 95%, a melting point of 50 to 150 ° C., and a number average molecular weight of 500 to 1,000,000. An electrophotographic toner wherein (A) is a resin particle (C) formed by forming a film made of fixed or fine resin particles (A) on the surface of a resin particle (B) made of resin (b) Resin particles. The resin particles can be produced using carbon dioxide (X) in a liquid or supercritical state. [Selection] FIG. |
