A powder feeding container is made from paper, resin film, or a synthetic film made with paper and resin film, the container containing powder within, and having a peak at one end, which is formed from an incline that starts from a middle of one edge of the container. The peak end is cut to form a first opening that releases the inside powder, whereas a change proximity area that starts forming an inclined edge is cut, and the rear area from the incision is folded inward, so that air is sent into the first opening along the inner wall of the inclined edge, forming a second opening.
