Toner cartridge movable in detachment direction by reverse rotation of coupler

An example toner cartridge includes a housing for accommodating toner and having a toner discharge port at one side; a conveying member inside the housing to rotate to convey the toner toward the toner discharge port; a driven coupler rotated by the rotational force; and an ejector rotated by the driven coupler. Any one of the driven coupler and the ejector is rotatably supported by a side wall of the housing in a longitudinal direction, and is connected to the conveying member to rotate the conveying member. When the driven coupler rotates in the opposite direction, the other one of the driven coupler and the ejector moves relative to any one of the driven coupler and the ejector in the direction spaced from the side wall. The reverse direction is a direction opposite to a forward direction in which the toner is conveyed toward the toner discharge port. 示例调色剂盒包括：壳体，用于容纳调色剂并且在一侧具有调色剂排出端口；输送构件，在所述壳体内，用以旋转以朝所述调色剂排出端口输送调色剂；从动联接器，通过旋转力旋转；以及顶出器，通过所述从动联接器旋转。所述从动联接器和所述顶出器中的任一个由所述壳体的在纵向方向上的侧壁可旋转地支撑，并且连接到所述输送构件以使所述输送构
