A powder feeding apparatus drops powder from a tank storing the powder to an oblique portion, and accumulates the powder on a plate disposed below the oblique portion. The plate is provided with a flat surface portion and a groove portion which is inverted from the flat surface portion to a lower part. The scraper moves powder which has accumulated to a higher level than a constant height on the flat portion and the groove portion, to an outer-side of the flat portion and smoothes the powder on the flat portion and the groove portion to a constant height. An ejector takes in powder which has accumulated on the groove portion of the plate by a suction opening, disposed at a front side of the scraper, in a relative moving direction of the plate, and discharges the powder from the discharge opening.
