Abstract: A method of manufacturing a liquid ejection head includes the steps of (1) forming a recess in a second surface of a substrate to form a common supply port, (2) forming an etching mask, which specifies opening positions of independent supply ports, on a bottom surface of the common supply port, and (3) performing ion etching using plasma with the etching mask employed as a mask, thereby forming the independent supply ports. The etching mask has an opening pattern formed therein such that respective distances from an ejection energy generation element to openings of two independent supply ports adjacent to the ejection energy generation element on the first surface side of the substrate are equal to each other.

Abstract: An ink jet print head is provided which can improve throughput by increasing an ink ejection frequency and prevent crosstalk among a plurality of heat application portions, realizing a capability of printing high-quality images at high speed. An opening size of the supply ports in a direction perpendicular to the array direction of the heat application portions is made greater than the length in the direction of electrothermal conversion elements. The supply ports are arranged along the array direction so that they adjoin the heat application portions in the array direction.

Abstract: Provided is an inkjet print head in which, without causing an increase in print head size, printing elements that can perform ejection at a high frequency are densely arrayed. For this purpose, an ink supplying port and a wiring line, which are common to a predetermined number of printing elements, are prepared, and a substrate on which the ink supplying ports and the wiring lines are alternately arranged at the same pitches as an array pitch of the printing elements is also prepared.

Abstract: An ink jet print head is configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. An individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber are symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of the pressure chamber.

Abstract: Disclosed is a liquid discharge method of discharging liquid with a liquid discharge head having a heating surface that contacts and heats the liquid and a discharge port that faces the heating surface and discharges the liquid. The method includes heating the liquid through the heating surface to generate a bubble such that the bubble communicates with an atmosphere, thereby discharging the liquid. The liquid that is being discharged from the discharge port includes a trailing portion. The trailing portion moves toward the heating surface in response to a reduction in volume of the bubble and contacts the heating surface. The method further includes heating the trailing portion through the heating surface while the trailing portion is in contact with the heating surface, thereby generating a bubble.

Abstract: A liquid ejecting head ejects liquid from a plurality of ejection orifices thereof for recording while being moved relative to a recording medium. The liquid ejecting head includes a gas discharge port configured to allow gas to be discharged therefrom. The gas discharge port is disposed on a downstream side of the ejection orifices in a direction of relative movement of the recording medium as viewed from the liquid ejecting head. The gas discharged from the gas discharge port joins an airflow that forms a vortex on an upstream side of the ejection orifices in the direction of relative movement. The vortex is generated by the liquid ejected from the ejection orifices.

Abstract: Gas is ejected toward a region between a liquid ejection head and a recording medium so as to enlarge and stabilize a vortex generated by an airflow generated by liquid droplets ejected from ejection ports. Accordingly, an airflow turbulence generated between the liquid ejection head and the recording medium is reduced and displacements of positions at which the liquid droplets are applied due to the airflow turbulence are reduced.
