    摘要： A liquid ejecting head includes plural ejection outlets for ejecting droplets; liquid flow paths in fluid communication with the ejection outlets; and a liquid supply opening for supplying the liquid to the liquid flow paths. The ejection outlets include first and second ejection outlets disposed at least at one side of the liquid supply opening and are staggered. The first ejection outlets are nearer to the liquid supply opening than the second ejection outlets. Each of first recording elements corresponding to the first ejection outlets includes one rectangular heat generating resistor having a long side extending along a direction crossing with an arranging direction of the ejection outlets. Each of second recording elements corresponding to the second ejection outlets comprises plural rectangular heat generating resistors which are adjacent to each other at long sides thereof and are electrically connected in series.

    摘要： An object of the present invention is to provide an ink jet print head having plural types of nozzles arranged on the same substrate and through which ink droplets of different sizes are ejected, the ink jet print head exhibiting acceptable ejection performance regardless of the type of the nozzle. Thus, according to the present invention, each of the plural types of nozzles includes a bubbling chamber having an ejection energy generating element allowing an ink droplet to be ejected to a position located opposite an ejection port and an ejection port portion allowing the ejection port and the bubbling chamber to communicate with each other. Ratio of opening area of the ejection port portion at a position where the ejection port portion and the bubbling chamber communicate with each other, to the opening area of the ejection port is higher for the nozzle with a smaller ejection amount.

    摘要： The present invention provides a print head that allows the characteristics of ejected ink to be adjusted for each ejection port in spite of a variation in the distance from an ink supply port to the heating element. In the print head according to the present invention, the area of the heating element decreases with increasing distance from the ink supply port and increases with decreasing distance from the ink supply port. The heating element is shaped like a rectangle that is longer in a direction orthogonal to a direction in which the plurality of ejection ports are arranged than in the direction in which the plurality of ejection ports are arranged. The aspect ratio of the heating element depends on the length of an ink channel through which ink is introduced into the bubbling chamber.
