Abstract
A developer cartridge includes a developer storing portion that stores a developer and has a first opening for taking out the developer, and a shutter member slidably mounted to the developer storing portion so as to open and close the first opening. The shutter member has a resilient-member-fixing portion to which a resilient member is fixed for preventing leakage of the developer through between the shutter member and the developer storing portion. A deflectable part is provided on at least one of the resilient-member-fixing portion and a peripheral portion of the first opening of the developer storing portion.
