摘要：
A substrate for an ink-jet element of an ink-jet printing head which ejects ink through ejection openings includes heating elements provided for each of the ejection openings and which generate thermal energy for ejecting the ink, a data holding circuit for holding an image data for driving the heat generating elements, by holding the image data in the number of bits corresponding to the number of ejection openings, and a driving circuit for driving the heating elements in units of the plural heating elements provided for each of the plural ejection openings based on the image data. A selection circuit selects at least one of the plural of heating elements provided corresponding to each of the ejection openings for driving. An ink-jet printing head and ink-jet printing apparatus employ such a substrate.
