PROBLEM TO BE SOLVED: To provide a structure of a device using powder which hardly causes defective feed of powder after actuation even if powder is already housed in the device before the actuation.SOLUTION: A powder feed device includes: a cylindrical casing 41 having an opening 41a that receives powder sent from a powder housing portion housing the powder; a transport member 42 that is arranged in the casing, extends in a transport direction, rotates and transports the powder received in the casing 41 through the opening 41a; and a shutter member 43 that is arranged at a closed position at which the opening 41a is closed before an initial rotation of the transport member, and that moves to an open position at which the opening 41a is open upon receiving force from the transport member by the initial rotation of the transport member. The transport member 42 includes: a transport portion 42A that contributes to the powder transport; and a non-transport portion 42B that does not contribute to the powder transport and handles the movement of the shutter member 43 to the open position. The shutter member 43 moves to the open position upon receiving an effect of the non-transport portion 42B. |
