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 which includes 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.
