A powder developer holding apparatus prevents developer leakage. A housing (43) holds powder developer, and includes a discharging opening (44) through which the powder developer is discharged. A shutter (42) is mounted to the housing (43) and is rotatable relative to the housing (43) to an opening position where the discharging opening (44) is opened or to a closing position where the discharging opening (44) is closed. A locking member (54, 69) is slidably mounted to the shutter (42). When the powder developer holding apparatus is oriented such that the discharging opening (44) faces upward in a gravitational direction, the locking member (54, 69) prevents the shutter from rotating relative to the chamber. |
