Head member, method for ink-repellent treatment and apparatus for the same

摘要

Disclosed are a head member having an ink-repellent film high in ink repellency, a method of ink-repellent treatment for the head member and an apparatus for the same. A head member ( 15 ) including a plurality of ejection ports ( 14 ) to eject ink comprises an ink-repellent film ( 25 ) on a surface having the ejection ports ( 14 ) open thereon, the ink-repellent film made of fluorocarbon resin subjected to plasma polymerization on the surface. An ink-repellent treatment method includes the steps of: disposing the head member ( 15 ) in a chamber ( 31 ) maintained in a vacuum state; introducing gaseous linear perfluorocarbon as a material of an ink-repellent film into the chamber ( 31 ); and depositing an ink-repellent film ( 14 ) made of fluorocarbon resin obtained by subjecting the perfluorocarbon to plasma polymerization on the surface of the head member ( 15 ) to perform the ink-repellent treatment.
