Abstract:
A sieving device including a hollow cylindrical body, a filter disposed at a bottom portion of the hollow cylindrical body, and a blade configured to rotate in close proximity to the filter around a rotation axis thereof crossing the filter to thereby stir powder supplied to the hollow cylindrical body.
Abstract:
A packing box of a polygonal tube shape to pack an object includes a plurality of corners and a plurality of holding portions. The plurality of corners are creases along which a flat plate is folded. The plurality of holding portions protrude inward of the packing box, hold the object, and are disposed at positions corresponding to at least two corners of the plurality of corners on one end in a longitudinal direction of the packing box and at positions corresponding to at least two corners of the plurality of corners on the other end in the longitudinal direction of the packing box that is a direction in which the polygonal tube shape extends. The at least two corners on the one end are different from the at least two corners on the other end.

Abstract:
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.
