Beschreibung
Zusammenfassung:	The present invention efficiently provides a polyester resin powder mixture having a small average particle size, excellent powder flowability, and high strength after molding. This polyester resin powder mixture is obtained by blending 0.1-5 parts by weight of silica microparticles having an average particle size of 20-500 nm in 100 parts by weight of a polyester resin powder having an average particle size that is over 1 µm and is less than or equal to 100 µmm, and that has a uniformity of 4 or less.
