An ink jet recording apparatus in which a filter F for ink filtration is slanted to a horizontal surface and provided in an ink supply channel communicating with an ink supply port of an ink jet head in a position higher than the ink supply port. In this arrangement, bubbles moved from the ink jet head are collected to a part of the periphery of the filter and easily passed through holes of the filter. As spread and stay of bubbles can be prevented, the ink can be supplied in a stable manner, and further, the occurrence of ink discharge failure can be reliably suppressed.
