Summary:To prevent, in a developer storage container including therein a movable wall for conveying developer, the developer from being excessively discharged from a developer discharge port by a cleaning member that cleans a detection surface to be a detection area of a detection sensor that detects developer.SOLUTION: A toner container 30 comprises, in an internal space of a container body 31, a movable wall 34 that moves in a first direction along a shaft part 33; and a rotating body 35 that rotates around the shaft part 33. The rotating body 35 has a cleaning unit 41 including a cleaning film 45. The cleaning film 45 is in slide contact with a toner detection surface 31B to clean the toner detection surface in association with the rotation of the rotating body 35. The cleaning film 45 has a projection piece 453 that is provided in a tip area 451 in a projecting manner and interferes with an opening peripheral part of a toner discharge port 30P. The projection piece 453 moves the tip area 451 while in slide contact with an inner peripheral surface 31A in association with the rotation of the rotating body 35, and when the tip area reaches the toner discharge port 30P, prevents the tip area 451 from being fitted into the toner discharge port 30P.SELECTED DRAWING: Figure 17 【課題】現像剤を搬送する移動壁を内部に備えた現像剤収容容器において、現像剤を検知する検知センサーの検知領域となる検知面を清掃する清掃部材によって、現像材が過剰に現像剤排出口から吐出させない。【解決手段】トナーコンテナ３０は、コンテナ本体３１の内部空間には、シャフト部３３に沿って第１方向へ移動する移動壁３４と、シャフト部３３回りに回転する回転体３５とを含む。回転体３５は、清掃フィルム４５を備えた清掃部４１を有する。清掃フィルム４５は、回転体３５の回転に伴い、トナー検知面３１Ｂに摺接して清掃する。清掃フィルム４５の先端領域４５１には、トナー排出口３０Ｐの開口周縁部と干渉する突片４５３が突設されている。突片４５３により、先端領域４５１が回転体３５の回転に伴って内周面３１Ａと摺接しつつ移動し、トナー排出口３０Ｐに到達した際に、当該トナー排出口３０Ｐへの先端領域４５１の嵌り込みが防止される。【選択図】図１７
