摘要:
A powder discharging device of the present invention includes a powder container storing powder therein and including a bottom wall formed with an outlet at one end portion for discharging the powder vertically downward. A container moving device moves the powder container toward the above end portion and then generates an acceleration opposite in direction to the movement of the powder container in the powder container to thereby cause the powder to move toward the outlet. The maximum value of the acceleration is between 40 m/sec2 and 200 m/sec2 while a period of time for which the container moving device continuously generates an acceleration of 20 m/sec2 or above is between 3 msec and 30 msec.
