SOLUTION: This powder comprises plural resin compositions composed of polyamides as constitutent substances. The powder is further blended with (A) a colorant (e.g. carbon black), (B) a stabilizer (e.g. a heat resistant stabilizer) and (C) an additive (e.g. a plasticizer) in a molten state. Preferably, the powder has 20-80μm average particle diameter (median diameter) and nylon 12, etc., may be used as the component A.
