Abstract
The conveying screw includes a conveying blade and a pair of supporting portions. The conveying blade is provided spirally along a conveyance direction of powder. The pair of supporting portions is provided at both end portions of the conveying blade in the conveyance direction. The conveying blade is formed by alternately arranging a plurality of semicircular blade plates on one side and the other side across a rotational center, and connecting the one blade plate and the other blade plate adjacent to the conveyance direction. One blade plate and the other blade plate adjacent to the conveyance direction constitute a pair of blade plates having reversed inclinations with respect to the conveyance direction. A part of the pairs of blade plates constitutes a large-diameter blade part having a larger outer diameter than the other part of the pairs of blade plates.
