A recording apparatus having a diaphragm valve disposed between an ink tank and a recording head, in which closing and opening the valve produces a flow of ink. The ink tank includes two independent connection ports adjacent to one end at the bottom and a structure being configured to restrict an upward flow of ink and being located above the connection ports. Restricting the upward flow allows a small amount of ink flowing in and out to produce an entire flow of ink within the ink tank. Therefore, variations in concentration caused by precipitation of ink can be reduced.
