An image forming device includes photosensitive drums, developer cartridges, an endless belt, first collecting units, first conveying units, a second collecting unit, a second conveying unit and communication portions. The photosensitive drums form a drum array including a leading photosensitive drum. Each developer cartridge has a waste developer accommodating chamber. Each first collecting unit collects waste developer on the corresponding photosensitive drum. Each first conveying unit conveys the waste developer toward the waste developer accommodating chamber. The second collecting unit collects waste developer on the endless belt. The second conveying unit conveys the waste developer toward the waste developer accommodating chamber. Each communication portion allows fluid communication between the first conveying unit and the waste developer accommodating chamber. One of the communication portions associated with the leading photosensitive drum also allows fluid communication between the second conveying unit and the waste developer accommodating chamber.
