ABSTRACT:
An ink jet printer includes ink jet heads for recording an image on a recording medium, an ink bottle for holding ink, an ink supply path connecting the ink bottle to each ink jet head, and an electromagnetic valve provided on the path. In the printer, the bottle, the valve and the heads are arranged downward in this order in the vertical direction, the path constantly exists upwards in the vertical direction in such a manner that air entered into the path moves up above the valve due to a difference in the specific gravity between the air and the ink, the path is provided with a branching portion provided between the valve and the heads, and a sub ink tank is provided at an end of the branching portion so as to be positioned lower than the heads in the vertical direction.
