<P>PROBLEM TO BE SOLVED: To prevent aggregation of toner around a toner discharge port. <P>SOLUTION: A toner discharge device comprises a toner discharge member and a toner discharge part. The toner discharge part includes a toner discharge port formed by opening a part area in the vicinity of the vertically lower side of a cylindrical wall. The toner discharge member is positioned facing a rotation shaft and the toner discharge port in the vicinity of one end part of the toner discharge part, and includes: a toner discharge plate fixed on the rotation shaft in the upper vertical direction of the toner discharge port; an elastic spiral blade whose one end part is fixed to the toner discharge plate to connect therewith, and includes a telescopic blade in the rotation shaft direction; and a spiral blade part which is on the rotation shaft extended to the toner storage part direction in the vicinity of the other end part of the toner discharge part, and which includes blades fixedly provided in an area of the rotation shaft where neither a toner discharge plate nor an elastic spiral blade is formed. The toner discharge device is characterized in having such the constitution and conveying toner in the toner discharge port direction by rotating the toner discharge plate, the elastic spiral blade and the spiral blade part around the rotation shaft. <P>COPYRIGHT: (C)2013,JPO&INPIT |
