Summary:PROBLEM TO BE SOLVED: To recover a deteriorated developer simultaneously with the supply of developer with a compact and simple configuration.SOLUTION: There is provided a developer supply container detachably attached to an apparatus body of an image forming apparatus and supplying developer to the apparatus body, the developer supply container including a developer storage bag that accommodates developer, a developer discharge path for discharging the developer accommodated in the developer storage bag, a developer introduction path for introducing a developer remaining in the apparatus body to the developer supply container, a recovered developer storage unit that is provided in a space between a container frame body and the developer storage bag and accommodates the developer recovered from the apparatus body through the developer introduction path, and opening/closing means capable of opening and closing the developer introduction path. When the opening/closing means is closed, a state of negative pressure is maintained, and when the opening/closing means is opened, the developer remaining in the apparatus body is introduced to the recovered developer storage unit through the developer introduction path and the developer accommodated in the developer storage bag is discharged to the apparatus body through the developer discharge path. 【課題】小型で簡便な構成で、現像剤を補給するのと同時に劣化した現像剤を回収する。【解決手段】画像形成装置の装置本体に着脱可能で、装置本体に現像剤を補給する現像剤補給容器であって、現像剤を収容する現像剤収容袋と、現像剤収容袋に収容されている現像剤を排出する現像剤排出路と、装置本体に残留する現像剤を現像剤補給容器に導入する現像剤導入路と、容器枠体と現像剤収容袋との間の空間に設けられ、現像剤導入路により装置本体から回収した現像剤を収容する回収現像剤収容部と、現像剤導入路を開閉可能な開閉手段とを具備し、開閉手段が閉じている場合に負圧状態を維持し、開閉手段が開いた場合に装置本体に残留している現像剤が現像剤導入路から回収現像剤収容部へ導入され、現像剤収容袋に収容されている現像剤が現像剤排出路から装置本体へ排出される。【選択図】 図６
