Abstract: A powder leveler includes: a structure having an internal space in which powder moves; a sheet-shaped leveling member that rotates while having a first end thereof attached to a rotation shaft disposed inside the structure, and that comes into contact with part of the powder accumulating at a portion inside the structure close to a free end thereof located away from the rotation shaft to level out the powder; and an obstacle located inside the structure at a position on a rotation path of the leveling member to obstruct the rotation path, the obstacle allowing the leveling member to pass thereby while the leveling member is rotating and being bent as a result of partially coming into contact with the obstacle.
