To provide a technique capable of improving the assemblability of a developer container while suppressing developer leakage from the developer container.SOLUTION: A developer container includes: a container member; a coupling member attached to an opening of the container member; and an exhaust passage formation member coupled to the container member through the coupling member and forming an exhaust passage for exhausting a developer from a storage part of the container member. The coupling member includes a part to be inserted having an open hole and a part to be engaged. The exhaust passage formation member includes an insertion part inserted into the open hole of the part to be inserted and an engagement part provided in correspondence with the part to be engaged. In a state in which the insertion part is inserted into the part to be inserted, relative rotation with a predetermined rotation axis as a central axis between the coupling member and the exhaust passage formation member brings the part to be engaged and the engagement part into an engagement state with each other through a process in which at least one of the coupling member and the exhaust passage formation member is elastically deformed. In the engagement state, the developer container regulates relative displacement between the coupling member and the exhaust passage formation member in the rotation axis direction.SELECTED DRAWING: Figure 31 【課題】現像剤容器からの現像剤漏れを抑制しつつ、現像剤容器の組立性の向上を図ることができる技術を提供する。【解決手段】容器部材と、容器部材の開口部に取り付けられる結合部材と、結合部材を介して容器部材に結合され、容器部材の収容部から現像剤を排出するための排出路を形成する排出路形成部材と、を備える現像剤容器であって、結合部材は、貫通孔を有する被挿入部と、被係合部と、を有し、排出路形成部材は、被挿入部の貫通孔に挿入される挿入部と、被係合部に対応して設けられる係合部と、を有し、被係合部と係合部は、挿挿入部が被挿入部に挿入された状態において、結合部材と排出路形成部材との間で所定の回転軸線を中心軸とする相対回転によって、結合部材と排出路形成部材の少なくとも一方が、弾性変形する過程を経て互いに係合した係合状態となり、係合状態において、結合部材と排出路形成部材との回転軸線方向における相対移動を規制する。【選択図】図３１
