PROBLEM TO BE SOLVED: To provide an inkjet recorder in which ink can be circulated stably and supplied to an ejection head even if ink is ejected continuously from the ejection head by preventing evaporation of solvent. SOLUTION: The recorder 10 comprises an ejection head 12 and an ink circulation system 20. The ink circulation system 20 comprises a main tank 14, a supply subtank 16 for supplying ink to the ejection head by a static pressure system, a supplement liquid tank 22, and interconnecting piping 50. A passage for circulating ink of the ink circulation system 20 is formed to be sealed hermetically from the atmosphere. At least a part of the ink circulation system 20 is provided with a pressure regulator for regulating the inner pressure of the ink circulation system. The pressure regulator is formed of a soft material exhibiting flexibility. COPYRIGHT: (C)2006,JPO&NCIPI |
