Abstract
A powder container includes a bottle body that accommodates powder and has, at one end, an opening through which the powder flows out. The bottle body is positioned with the opening facing laterally and set rotatable about a rotation center line extending laterally through a center of the opening. The bottle body has an inner peripheral surface on which a spiral protrusion is formed to transport the accommodated powder toward the opening through the rotation. When the bottle body is sectioned vertically on a plane including the rotation center line, the spiral protrusion causes plural upwardly protruding projections to appear on a cross-section, the plural projections include a first projection and a second projection closer to the opening than the first projection, and an opening-facing face of the second projection has a bottom lower than a top of the first projection or the opening has a lower edge lower than the top of the first projection.
