Abstract:
A powder container includes a powder container body having a cylindrical form to store powder. The powder container body includes a conveyer, a large diameter portion, a small diameter portion, and a boundary portion. The conveyer conveys the powder stored in the powder container body in a longitudinal direction of the powder container body. The large outer diameter portion has an outer diameter on a cross section orthogonal to the longitudinal direction. The small outer diameter portion has an outer diameter smaller than the outer diameter of the large outer diameter portion on the cross section. The boundary portion connects the large outer diameter portion and the small outer diameter portion.
