To make it possible to reduce the size of a moving member along the axial direction of a shank, while maintaining the performance to remove a powder attached to a conveying member between a blade and a blade.SOLUTION: A conveying device comprises: a conveying member that has a shank and blades formed spirally on an outer peripheral surface of the shank, and conveys a powder through the rotation of the shank; and a moving member that extends from the outside in the radial direction with respect to the conveying member toward the shank and has its tip moving along the axial direction of the shank between the blade and the blade.SELECTED DRAWING: Figure 7 【課題】羽根と羽根との間で搬送部材に付着した粉体を落とす性能を維持しつつ、軸部の軸方向に沿った移動部材の大きさを小さくできるようにする。【解決手段】軸部と、該軸部の外周面に螺旋状に形成された羽根と、を有し、該軸部の回転により、粉体を搬送する搬送部材と、前記搬送部材に対する径方向外側から前記軸部へ延び、先端部が前記羽根と前記羽根との間で前記軸部の軸方向に沿って移動する移動部材と、を備える。【選択図】図７
