The casing includes a first toner accommodating portion having an opening. The first cover and the shutter are positioned at one end portion of the first toner accommodating portion in the first direction. The first cover has a discharge opening. The shutter has a shutter opening and a first protrusion extending in the first direction and positioned farther from the one end portion of the first toner accommodating portion than the first cover is in the first direction. When the toner cartridge is mounted to a developing device, the first protrusion is fixed in position relative to the developing device and the casing is pivotable together with the first cover relative to the developing device.
