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.
