Abstract
A development cartridge which is mountable in an image forming apparatus includes a toner container portion to store toner and a toner refilling portion to receive, from a toner refill cartridge mountable to the toner refilling portion, toner to be stored in the toner container portion. The toner refilling portion includes an inlet shutter rotatable to an inlet position at which the toner is capable of being received by the toner refilling portion from the toner refill cartridge, and a shutter protrusion provided on a surface of the inlet shutter to, while the inlet shutter is rotated, contact an object and cause feedback indicating the inlet shutter is rotated to the inlet position.
