The present invention provides an ink jet print head that allows for a fast printing of high-density, high-quality images without increasing cost and size of the print head. To this end, the ink jet print head has orifices for ejecting ink of a first volume and orifices for ejecting ink of a second volume, the second volume being smaller than the first volume. Further, the number of orifices for first-volume ink per unit length is greater than the number of orifices for second-volume ink per unit length.
