    Abstract: An inkjet recording apparatus includes a sheet conveying unit, a storage unit, a line head, and a control unit. The line head includes an upstream-side head and a downstream-side head. The upstream-side and downstream-side heads are fitted to have overlapping portions in which a plurality of nozzles arranged in respective end portions of the heads overlap as seen from the sub scanning direction. When an adjustment chart is printed, the control unit makes the nozzles in the overlapping portion of the upstream-side head print a first line. The control unit makes the nozzles in the overlapping portion of the downstream-side head print a second line.

    Abstract: A liquid ejection head includes a plurality of pressurizing chambers connected to a plurality of ejection holes, a plurality of first individual flow paths connected to the plurality of pressurizing chambers, a plurality of second individual flow paths and a plurality of third individual flow paths, a first common flow path is connected in common to the plurality of first and second individual flow paths, and a second common flow path is connected in common to the plurality of third individual flow paths. The first and second individual flow paths are connected to the same pressurizing chamber, the first individual flow path is connected to the first common flow path on a side of an opening end portion, compared to the second individual flow path. The first individual flow path is located opposite to a side where the ejection hole is open outward, compared to the second individual flow path.

    Abstract: The present invention provides a liquid ejecting module capable of performing stable ejection operation while circulating and supplying fresh ink to the vicinity of ejection ports arranged in high density. To achieve this, a liquid ejecting module includes an element arranged face in which a plurality of ejecting elements are arranged, a circulation flow path including a supply flow path which supplies liquid to a pressure chamber and a collection flow path which collects liquid from the pressure chamber, and a liquid delivery mechanism provided in the circulation flow path for circulating liquid in the pressure chamber. The liquid delivery mechanism is located lower than the element arranged face.

    Abstract: An object of the present invention is to provide an ink jet recording method capable of recording a high-quality image in which occurrence of unevenness is decreased. The ink jet recording method is a method of recording an image by ejecting ink from a recording head including an ejection orifice ejecting the ink, an ejection element generating energy for ejecting the ink, and first and second flow paths which communicate between the ejection orifice and the ejection element and in which the ink flows. The ink jet recording method includes: an ejection step of ejecting the ink from the ejection orifice; and a flow step of flowing the ink in the first flow path to the second flow path separately from the ejection step, wherein the ink is aqueous ink containing a pigment and a specific compound having an ethylene oxide group.
