    摘要： A manufacturing method for a print head, in which a substrate member provided with heating elements is laminated to a nozzle-formed member in which ink-ejection nozzles are formed, includes the step of laminating a correcting member having approximately the same coefficient of linear expansion as the substrate member to the nozzle-formed member. A nozzle interval L1 of a nozzle-formed member which doesn't laminate a correcting member at an operating temperature T0 is determined as =L2(1+&agr;2&Dgr;T)/(1+&agr;1&Dgr;T), wherein L2 is the nozzle interval and a heater interval at the operating temperature after the print head is completed; &agr;1 and is the coefficient of linear expansion of the nozzle-formed member; &agr;2 is the coefficient of linear expansion of the correcting member; T1 is the laminating temperature of the nozzle-formed member and the correcting member; and &Dgr;T is the difference between the laminating temperature T1 and the operating temperature T0.

    摘要： An inkjet print head includes one nozzle sheet (23) and a plurality of head chips (25) including a plurality of heaters. The nozzle sheet (23) is formed of an electroformed metal layer made of nickel or a material comprising nickel, and has discharge nozzle rows for respective colors disposed so that the discharge nozzles are in staggered arrangements and so that each set of discharge nozzles partly overlaps another set of discharge nozzles in a sheet-feed direction. The head chips are positioned at and affixed to a growth surface side of the nozzle sheet (23) in staggered arrangements so that the positions of the discharge nozzles and the positions of the heaters correspond to each other. Accordingly, reduction in printing quality caused by displacement of any of the discharge nozzles is prevented from occurring, and landing positions of discharged ink on a recording sheet are stabilized.

    摘要： A liquid ejecting apparatus can array dots in line even when nozzles are arranged in line and ink droplets are ejected from a plurality of liquid ejecting parts with a time difference.

The liquid ejecting apparatus further includes an ejecting-direction changing means that can change the droplet ejecting direction to a plurality of directions along the Y-direction by applying energy to the juxtaposed heating resistors in different manners, a time-difference ejection means that forms a dot (D2) by a second liquid ejecting part when a predetermined time elapses after a dot (D1) is formed by a first liquid ejecting part, and an ejecting-direction control means that makes the ejecting direction of the droplet from the first liquid ejecting part different from the ejecting direction of the droplet from the second liquid ejecting part so that the distance between the landing position of the dot (D1) in the first liquid ejecting part and the landing position of the dot (D2) in the second liquid ejecting part in the Y-direction is shorter than the relative moving distance between the head and printing paper.
