description To provide a developer supply device which is configured to convey developer in an elongate supply bottle from one end thereof toward a supply port at the other end in a longitudinal direction and which allows for recognizing an amount of remaining developer without having to move detection means.SOLUTION: Developer D piled up near a supply port 627 in a bottle body 61 is conveyed in a direction of the arrow β (in the figure) back to a detection region R of a detection sensor 63 disposed outside the bottle body 61 by reverse-rotating the bottle body 61, and a remaining amount of the developer is estimated from a result of detection by the detection sensor 63.SELECTED DRAWING: Figure 11 【課題】長尺の補給ボトル内の現像剤を長手方向一方端側から他方端側の供給口に向かって搬送する構成において、検出手段を移動させることなく現像剤の残量を知得することが可能な現像剤補給装置を提供する。【解決手段】ボトル本体61内で供給口627付近に片寄った状態の現像剤Dをボトル本体61の逆転により矢印β方向に搬送し、ボトル本体61の外に配置された検出センサー63の検出領域Rまで戻し、検出センサー63の検出結果から現像剤残量を推定する。【選択図】図11
