Abstract
A toner cartridge includes: a casing; a conveyer member rotatable about an axis; a shutter rotatable about the axis between a closed position and an open position; a toner coupling rotatable about the axis; a planet carrier rotatable about the axis with the toner coupling; a planetary gear rotatable about a pin of the planet carrier and rotatable about the axis in accordance with the rotation of the planet carrier; and a ring gear meshing with the planetary gear and rotatable about the axis with the shutter. When the shutter moves from the closed position to the open position, the planetary gear is not rotatable about the pin and is rotatable about the axis with the ring gear. In a state where the shutter is at the open position, the planetary gear is rotatable about the pin and is rotatable about the axis relative to the ring gear.
