摘要： An ink jet head movable in a main scan direction includes first and second groups of ejection outlet arrays disposed on either side of a common liquid chamber and including plural ejection outlet arrays. In the first group, amounts of liquid ejected from outlets of first and second ejection outlet arrays, which are staggered, differ from each other. In the second group, a common ejection amount ejection outlet array ejects the same amount of liquid as that of one of the first and second ejection outlet arrays and a non-common ejection amount ejection outlet array ejects an amount of the liquid that differs from that of the first ejection outlet array group. The ejection outlets of the common and non-common ejection amount ejection outlet arrays are disposed in a staggered arrangement. The ejection outlets of the second ejection outlet array group are disposed with deviation of ½ of an interval at which the ejection outlets of the first ejection outlet array group are arranged. Different sets of the same cyan and magenta colors in the non-common ejection amount ejection outlet arrays are disposed with deviation of ½ of an interval at which the ejection outlets of the non-common ejection amount ejection outlet arrays of other sets are arranged.

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.
