<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus where a developing device and a developer cartridge can be singly attached to/detached from a housing without leaking developer. <P>SOLUTION: A toner cartridge 39 is arranged to be opposed to the end (right end) in a width direction of a drum unit 38 nearly in a horizontal direction, and a supply port 116 inside a cartridge and a supply port 105 on a drum side are arranged to be opposed nearly in a horizontal direction, so that the drum unit 38 and the toner cartridge 39, which are attached to a main body casing 2, have no part where they are superposed on each other. Then, toner is prevented from being leaked from the supply port 116 inside the cartridge and the supply port 105 on the drum side further than, for example, when the supply port 116 inside the cartridge and the supply port 105 on the drum side are arranged to be opposed nearly in a vertical direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
