A process cartridge usable with an image forming apparatus includes a developing cartridge including a toner inlet and a shutter to open and close the toner inlet, and a toner cartridge detachably mounted to the developing cartridge and including a toner supply port to correspond with the toner inlet when connected with the developing cartridge. The shutter may be moved in a direction in which the toner cartridge is connected when the toner cartridge is connected to the developing cartridge, thereby opening the toner inlet, and the shutter may be moved in a direction in which the toner cartridge is detached when the toner cartridge is separated from the developing cartridge, thereby closing the toner inlet. Accordingly, when the toner cartridge is separated from the developing cartridge, the toner inlet of the developing cartridge is closed, thereby preventing leakage of toner through the toner inlet.
