Abstract
A developing cartridge and a developing device capable of preventing developer leak which may occur during replacement of a developer containing unit, and an image forming apparatus having the same are provided. The image forming apparatus includes an image forming apparatus body where a transfer path for a printing medium is formed, and a developing device for developing a visible image. The developing device may include, for example, developing cartridge, a developer containing unit, which contains a supply of developer therein, and which is detachably disposed in the developing cartridge to form a developer transfer path fluidly communicating with the developing cartridge, and a shutter unit which closes the developer transfer path when the developer containing unit is removed from the developing cartridge.
