PROBLEM TO BE SOLVED: To decrease fluctuation in density of a recorded image and to record an image with a high quality by bringing an ink path being an ink flow path for a fed ink to reach a common liq. room into close contact with the common liq. room so as to be along the common liq. room and forming it with the same member as that for the common liq. room. SOLUTION: A common liq. room 3 for holding an ink fed from an ink tank and an ink flow path 4 from the common liq. room 3 to an output hole 5 are formed each other of the same member. In addition, the output hole 5, the common liq. room 3 and the ink path 7 are brought into close contact with each other in this order and in parallel to the line of the output 5 from the output face. As the flow direction of the ink flowing in the ink path 7 being in parallel to the common liq. room 3 is reverse to the flow direction of the ink flowing in the common liq. room 3 thereby, the ink flowing in the high temp. part in the common liq. room 3 is cooled down with the ink in the ink path 7. As the result, there exists no possibility to generate a difference in temp. of the ink caused by the difference in the place in the common liq. room 3. |
