Abstract
A powder collecting container includes: a first chamber that is configured to store collected powder; a conveying unit that has a rotary shaft, and a powder conveying blade formed to be wound around the rotary shaft, the conveying unit being arranged along an upper-limit zone for accommodating powder in the first chamber and configured to convey powder which is contained in the first chamber and located at a position exceeding the upper-limit zone. A hollow member has an opening portion formed in a peripheral wall so that a powder conveying end of the conveying unit is located in the opening portion, and that the conveying unit passes through the hollow member. A second chamber has an inlet provided to face the opening portion so that powder conveyed by the conveying unit enters the second chamber from the inlet.
