TONER CONTAINER, IMAGE FORMING APPARATUS TO WHICH TONER CONTAINER IS ATTACHED

摘要

A toner container includes a container main body, a cylindrical portion, an opening/closing member, and a conveyance member. Container main body includes a storing chamber. Opening/closing member is provided in a inner space of cylindrical portion and, operates to open and close a toner discharge outlet of cylindrical portion. Conveyance member includes rotation shaft and blades along rotation shaft and when rotated, allows blades to convey the toner that is present inside storing chamber and the inner space toward toner discharge outlet. The plurality of blades include a first blade and a second blade. First blade is disposed in storing chamber at a position near a boundary between storing chamber and the inner space and is larger in outer diameter than the other blades. Second blade is disposed in the inner space and is larger than first blade in inclination angle with respect to rotation shaft of conveyance member.
