A packing member, a toner container, and a packing method. The packing member contains the toner container, and the packing member includes a box containing the toner container with a gap between one side of the box and a container body and between the one side of the box and a large-dimension portion of the toner container, a first pressing portion that presses the container body, and a second pressing portion that presses the large-dimension portion. In the packing member, the large-dimension portion of the toner container is disposed at one end of the container body, and the large-dimension portion has a wider dimension than the container body in a direction orthogonal to a longitudinal direction of the toner container. In the packing member, the container body contacts, with first contact force, a first bearer inside the box to maintain the gap.

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.
