PROBLEM TO BE SOLVED: To improve powder storage efficiency in a powder storage chamber in a powder recovery container including a fullness detection chamber adjacent to the powder storage chamber.SOLUTION: A powder recovery device 11 comprises: a recovery container 1 including one or more recovery ports 2 that recover a powder G conveyed from a powder processing part 10, a powder storage chamber 3 that initially stores the powder G recovered from the recovery ports 2, and a fullness detection chamber 4 that is provided adjacent to the powder storage chamber 3, stores the powder G overflown from the powder storage chamber 3, and detects whether the powder storage chamber 3 has become full with the powder G stored therein; and a conveyance member 7 that is provided inside the recovery container 1 and conveys the powder G stored in the powder storage chamber 3 toward the fullness detection chamber. The conveyance member 7 includes a first conveyance part 9a that is located on the upstream side in a direction of conveyance of the conveyance member 7, and a second conveyance part 9b that is located at a position adjacent to the fullness detection chamber 4 in the area of the powder storage chamber 3 and has a lower conveyance force than that of the first conveyance part 9a.SELECTED DRAWING: Figure 1 |
