PROBLEM TO BE SOLVED: To provide a developer cartridge that can suppress the visual recognition of dirt generated on a lid member and the periphery of a filling port in association with the filling of a developer.SOLUTION: In a developer cartridge 1, a lid member 80 is rotated from a filling port 63 to be located at an open position for filling the cartridge with toner. The lid member 80 is rotated to be located at a closed position for attaching a label 95 to a label attachment surface 62. At this time, the label 95 covers the outer periphery of the lid member 80 when the developer cartridge 1 is projected in the vertical direction, and thereby the label 95 can cover dirt attached to the periphery of the filling port 63 and the lid member 80. |
