Abstract: An inkjet head selectively ejects recording ink droplets and refresh ink droplets. The recording ink droplets are deflected so as to impinge on target locations on a recording medium, thereby forming recording dots thereon. On the other hand, the refresh ink droplets are deflected so as to impinge on an ink absorbing member. The ink clinging on the ink absorbing member is collected into an ink tank and reused. The ink absorbing member functions as a filter for preventing impurities being collected into the ink tank along with the ink.
