An image forming device includes a drive transfer device that selectively transmits a driving force of a first drive source to one of liquid feed pumps, a suction part of a maintenance recovery device and an air-vent opening part. The air-vent opening part is arranged to have a maximum driving-force transmission path leading to the drive transfer device among the liquid feed pumps, the suction part and the air-vent opening part. The maintenance recovery device, the drive transfer device and the liquid feed pumps are arranged in order in a sheet transport direction. The suction part of the maintenance recovery device and the drive transfer device are arranged on opposite sides of a cap of the maintenance recovery device in the sheet transport direction.
