摘要：: PROBLEM TO BE SOLVED: To provide a method of supplying powder to a forming mold and a powder supplying device, with which failure due to a recessed or a protruded part of accumulated powder or remained powder is improved and a higher quality is available for a compact of a powdery material such as a compressed powdery body. SOLUTION: A powder box 3 is moved to the mold opening 16 of a forming mold 1 while a scraping member 7 is separated from the upper face 14 of the forming mold 1, powder contained in a powder box 3 is charged into a forming cavity 15 through the mold opening 16 of the forming mold. Then the powder box 3 is retracted from the mold opening 16 along the upper face 14 of the forming mold 1. The scraping member 7 is moved along the upper face 14 of the mold in the opposite direction of the retraction while a scraping part 7a is in contact with or approached to the upper face 14 of the mold, thus remained powder remaining on the upper face 14 of the mold is made reach to the forming cavity 15, and at the same time, the mold opening 16 of the forming mold 1 is scraped by the scraping member 7 so that the upper face of accumulated powder in a forming cavity 15 in uniformalized.
