PROBLEM TO BE SOLVED: To provide a conveyance tool for reducing force to a developer sandwiched between the outer edge of the conveyance tool and an inner surface of the developer container when the conveyance tool is rotated in the developer container.SOLUTION: In the conveyance tool 20, arc conveying members 24A-24P are formed in a zigzag shape on the right and left sides of a rotary shaft 21 from the upstream side of the conveyance direction. Assuming that the distance from the center of the rotary shaft 21 to the outer edge of a fixed end 26 is r1 and the distance from the center of the rotary shaft 21 to the outer edge of a free end 27 is r2, the relation becomes r1<r2. Assuming that the distance between the outer edge of the fixed end 26 and the inner surface of a container body 11 is S1 and the distance between the outer edge of the free end 27 and the inner surface of the container body 11 is S2, the relation becomes S1>S2. The conveyance efficiency is higher on the free end 27 side than on the fixed end 26 side. |
