<P>PROBLEM TO BE SOLVED: To reduce passage failure caused by a mass of powder in a powder supply port and a powder conveyance path when supplying powder to another powder conveyance path adjacent to the former powder conveyance path via a powder supply port. <P>SOLUTION: The powder supply member includes: a powder storage container 1 that has a powder storage container 2 and a powder supply member 4 for supplying powder to the powder supply port 3; and a powder conveying unit 7 that is disposed adjacent to the powder storage container 1 via the powder supply port 3, has the powder conveyance path 8 extending along a predetermined direction in it, and conveys powder by a powder conveying member 9 along the predetermined direction. The powder supply member 4 has blades 6a different in length in a radial direction. The powder supply member 4 satisfies: the condition in which the radial length L of the upstream side is greater than the radial length L of the downstream side and the upstream side has a portion longer than the radial length L of the downstream side; or the condition in which, of the blades 6a, the radial length L of the upstream side in the powder conveyance direction of the powder conveyance path 8 is greater than the radial length L of the downstream side and the downstream side has a portion shorter than the radial length L of the upstream side. <P>COPYRIGHT: (C)2010,JPO&INPIT |
