1. A toner refilling cartridge for installation in an image forming apparatus in a direction of gravity to refill toner, the toner refilling cartridge comprising:
a body to contain toner, and comprising a toner outlet to discharge the toner to an outside of the toner refilling cartridge;
an agitating member to rotate about a central axis of the body and agitate the toner in the body;
a shutter member to move along the central axis with respect to the body, the shutter member comprising an open position to open the toner outlet and a blocked position to block the toner outlet;
a driving force receiver exposed to the outside through the toner outlet when the shutter member is in the blocked position, the driving force receiver to rotate by receiving a driving force from the outside; and
a driving shaft to transmit a rotational force of the driving force receiver to the agitating member,
wherein the driving shaft is to move in a direction of the central axis to connect with the agitating member, while the shutter member moves from the blocked position to the open position.
