Title: Inkjet recording head and its manufacturing method
Inventor: KANDA TORAHIKO
IPC: B41J2/135
Filed: 2004-08-10
Abstract: <P>PROBLEM TO BE SOLVED: To stabilize ejection characteristics by uniformalizing a state where a peripheral edge of a nozzle is wetted with ink.  <P>SOLUTION: The unwiped ink 600B is slightly left without being completely wiped even if being wiped by means of a wiper blade 120. A liquid-repellent film 210 is not formed on a stepped wall surface 200A of a step 200. This makes the ink more easily adhere to the wall surface 200A than to the peripheral edge of the nozzle 10. Thus, the unwiped ink 650 is left on the wall surface 200A without being wiped, and is not left in other places without being wiped. In other words, the unwiped ink 650 is positively left on the wall surface 200A without being wiped, so as not to be positively left on the peripheral wall of the nozzle 10 without being wiped. Such constitution prevents wetting from becoming nonuniform because the unwiped ink on the peripheral edge of the nozzle 10 accidentally remains, and prevents the destabilization of the ejection characteristics and a deterioration in printing quality.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
