Abstract

An ink jet head, including
  • (i) a plurality of discharging outlets (D; 4) disposed in an arrangement direction;
  • (ii) a plurality of ink pathways (31), each of said ink pathways (31) communicating with an associated one of said discharging outlets (D; 4), each of said ink pathways (31) having an energy generating element for generating energy for discharging an ink from said discharging outlet (D; 4); and
  • (iii) a discharging outlet face (1A; 8) having
  • a discharging outlet surface, said discharging outlets (D; 4) being arranged in said discharging outlet surface and
  • a water-repellent discharging outlet peripheral region (E; 7) circumscribing said discharging outlets (D; 4), and having a first side and a second side,
    herewith
  • a recessed hydrophilic region (9) circumscribing said water-repellent discharging outlet peripheral region (E; 7), said recessed hydrophilic region (9) being positioned along the arrangement direction of the discharging outlets (D; 4) on at least one said side of said water-repellent discharging outlet peripheral region (E; 7), said recessed hydrophilic region (9) being separated by a predetermined distance from said water-repellent discharging outlet peripheral region (E; 7).
