PROBLEM TO BE SOLVED: To stabilize the discharge of a developer from a discharge port without enlarging a device. SOLUTION: A surplus developer is discharged from the discharge port 64 to a reservoir room 62 by a flow as shown by an arrow M. Then, an upper end opens and a bottom end side forms a slope 60D toward the bottom end of the discharge port 64, while an opening and closing member 60 is opened. Consequently, the overflowed developer is guided to the discharge port 64 according to the guide of the slope 60D. Accordingly, the developer is discharged smoothly. In other words, the opening and closing member 60 plays both roles of switching the discharge port 64 and the guide for guiding the developer to the discharge port 64. COPYRIGHT: (C)2007,JPO&INPIT |
