A developer receiving unit (32) receives developer from a discharging unit (16). The developer receiving unit includes a path (62+ 71, 75+71, 75+76, 90+71) through which the developer is received from the developer discharging unit, the path adapted to expand and contract in length. The developer-receiving unit moves into sealed engagement with the developer-discharging unit so that the developer-receiving unit communicates with the developer-discharging unit through the path. An urging member (67) urges the path in such a direction as to expand in length. An opening-and-closing member (63, 66, 64) receives a drive force from the developer-discharging unit when the developer-discharging unit pushes the developer receiving unit, the drive force acting on the opening-and-closing member in such a way that the opening-and-closing member causes the path to open. The opening-and-closing member (63, 66, 64) opens the path only after the developer discharging unit moves into sealed engagement with the developer receiving unit. |
