<P>PROBLEM TO BE SOLVED: To reduce a force that an arcuate member receives from a developer on the downstream side than on the upstream side, when the conveyance tool is rotated in a developer cartridge, and the developer is conveyed from the upstream side to the downstream side in the developer cartridge and delivered. <P>SOLUTION: In this conveyance tool 20, arcuate conveyance members 24A-24L are formed in a zigzag shape right and left of a rotating shaft 21 from the upstream side of the conveyance direction. When the conveyance tool 20 (arcuate conveyance members 24) rotates in the arrow A direction in the developer cartridge Ky, two arc sections 25 push and convey the developer to the downstream side in the conveyance direction in a range where adjacent arcuate conveyance members 24 partially overlap. Therefore, in order to increase the conveyance efficiency when the developer is conveyed, the arcuate conveyance members 24 are arranged while the distance between adjacent arcuate conveyance members 24 is shortened so as to elongate the overlapping distance. <P>COPYRIGHT: (C)2011,JPO&INPIT |
