    摘要： A liquid ejection head 3 includes: a liquid ejection part 3a configured to eject a liquid; and a guide part 20b provided upstream of the liquid ejection part 3a with respect to a conveying direction A of a recording medium 2 and configured to guide the front end of a recording medium 2 conveyed to the liquid ejection part 3a. The guide part 20b has an inclined surface 20c inclined so as to be more spaced apart from a conveyance path for the recording medium 2 as the inclined surface 20c is more distant from the liquid ejection part 3a.

    摘要： An inkjet printing apparatus includes a print head, to which a protective member configured to protect an ejection opening surface is attachable, and a head holder configured to hold the print head detachably. The inkjet printing apparatus further includes a guide portion provided in the head holder and configured to guide, in a width direction, the print head with the ejection opening surface protected by the protective member. The guide portion guides the print head with the protective member attached up to a predetermined position in the width direction and guides only the print head ahead of the predetermined position to prevent the protective member from exceeding the predetermined position.

    摘要： A page-wide type liquid ejection head includes a plurality of recording element substrates, each having an ejection port array including a plurality of ejection ports, each ejection port communicating with a pressure chamber including therein a recording element, and a liquid supply path for supplying a liquid to the pressure chamber. The liquid ejection head also includes a flow path member mounting the recording element substrates arranged thereon. The flow path member includes common supply flow paths and individual supply flow paths that connect the liquid supply path to the common supply flow paths, and the individual supply flow paths include portions running obliquely to the direction orthogonal to the longitudinal direction of the liquid ejection head.
