NEW YORK, NY 10001-7708 (US) A liquid ejection apparatus includes: a liquid ejection head
(56) having a noZZle (51) for ejecting a droplet of charged
(73) Assignees: KONICA MINOLTA HOLDINGS, solution from the tip portion; an ejection electrode (58)
INC., Tokyo (JP); SHARP KABUSHIKI provided on the liquid ejection head, to Which a voltage is
KAISHA, Osaka (JP); NATIONAL applied for generating an electric ?eld to eject the droplet; a
INSTITUTE OF ADVANCED INDUS voltage applying unit (35) for applying the voltage to the
TRIAL SCIENCE & TECH ejection electrode; a substrate K including insulative mate
NOLOLGY, Tokyo (JP) rial for receiving the ejected droplet; and an ejection atmo
sphere adjusting unit (70) for keeping an atmosphere subject
(21) App1.No.: 10/567,484 to ejection from the liquid ejection head, to a deW point of
9 degrees centigrade or more and less than a Water saturation
