摘要： Without being dependent on design changes, a liquid ejection head and a method of production thereof are provided in which when time-division driving, liquid drop landing deviance in the direction of printing is capable of being corrected. In order to achieve this, before performing an exposure in order to form an ejection port, after forming a cavity that is shifted with respect to the location at which the ejection port is formed, exposure is performed.

摘要： An object of the present invention is to provide an ink jet recording apparatus which can keep an adequate absorptivity of an ink absorbing member for a long period of time, even when such inks which react with each other are sucked through the same cap in a sucking recovery operation, by preventing a mixed ink collected by the ink absorbing member from thickening or being solidified. The ink jet recording apparatus has: a recovery unit 8 and 62 for draining ink from a black-ink discharge portion 13 for discharging black ink and a color-ink discharge portion 14 for discharging color ink which reacts with the black ink; an ink absorbing member 31 for collecting the ink which is drained by the recovery unit and separating the ink into a solid part 41 and a liquid part 42; and an ink introduction unit 7 for introducing the ink which is drained by the recovery unit, into the ink absorbing member.
