PROBLEM TO BE SOLVED: To provide an inkjet head which can facilitate discharge of bubbles by preventing the bubbles from being large, and to provide an inkjet type recorder. SOLUTION: An electric heater 61 is set in the periphery of a filter chamber 32a of an ink supply needle 31. An outer wall of the filter chamber 32a is heated, so that a passage of the ink supply needle 31, particularly, an inner wall of the filter chamber 32a is heated. Thus a volume of the bubbles adhered to the inner wall is expanded. The bubbles are facilitated to separate from a wall surface and prevented from being large. COPYRIGHT: (C)2007,JPO&INPIT |
