POWDER CONVEYANCE DEVICE AND IMAGE FORMATION DEVICE

PROBLEM TO BE SOLVED: To break powder with a simpler constitution compared with the case that a powder breaking mechanism is formed by combining many components.SOLUTION: When a body side conveyance member 101 rotates in the circumferential direction, a first protrusion 408A is pressed by a projection 101B of the body side conveyance member 101. Thus, as shown by an arrow 5A, a receiving piece 405 moves in the extending direction of the receiving piece 405. When the receiving piece 405 moves, following this movement, second opposite piece 402 to fourth opposite piece 404 move in the direction separating from an inner wall 200 as shown by a broken-line 5B. When the pressing of first protrusion 408A by the projection 101B is released, a movable piece 400 is restored, and the movable piece 400 moves toward the inner wall 200. At this time, the movable piece 400 vibrates.SELECTED DRAWING: Figure 5 【課題】多数の部品を組み合わせて粉体を崩す機構を構成する場合に比べ、簡易な構成で粉体の崩しを行えるようにする。【解決手段】本体側搬送部材１０１が周方向に回転すると、第１凸部４０８Ａが、本体側搬送部材１０１の突出部１０１Ｂにより押圧される。これにより、矢印５Ａに示すように、受け片４０５が延びる方向へ受け片４０５が移動する。受け片４０５が移動すると、これに付随して、破線５Ｂで示すように、第２対向片４０２〜第４対向片４０４が、内壁２００から離れる方向へ移動する。突出部１０１Ｂによる第１凸部４０８Ａの押圧が解除されると、可動片４００は復元し、可動片４００は、内壁２００に向かって進出する。このとき、可動片４００は振動する。【選択図】図５
