A developer cartridge (728a) includes a developer supplying section (36) for supplying a developer to a photosensitive body cartridge and a developer housing section (30) for housing the developer. A projection (440) is arranged on an exterior surface of the developer housing, providing contact with the photosensitive body cartridge. When the developer cartridge is detachably attached to the photosensitive body cartridge, the projecting portion engages with the photosensitive body cartridge to press the developer supplying section towards the photosensitive body cartridge and to regulate movement of the developer cartridge. |
