LIQUID DISCHARGING HEAD, LIQUID DISCHARGING UNIT AND RECORDING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent occurrence of unevenness in a recording image at a gap of a plurality of isolation walls or a gap of a plurality of boards by making a discharging characteristic distribution uniform in a liquid discharging head having a plurality of boards and(or) a plurality of isolation walls. SOLUTION: A gap 35 is generated between a board 1a and a board 1b. Foaming pressure might be sometimes released via the gap 35. Thus, a shape of movable member 31b is formed so as to enhance a discharging efficiency to more sufficiently receive the foaming pressure corresponding to heaters 2 at ends of the boards 1a and 1b. Specifically, its size is increased more than that of the other movable member 31a. Thus, discharging characteristics of respective nozzles are made uniform, and hence no irregularity that a recorded image become pale in density does not occur on this part due to reduction in discharging amount caused by a decrease in an efficiency only at the ends of the boards 1a and 1b. The member 31b may be dealt with other parameter which can alter discharge characteristics such as position of a fulcrum or a free end in addition to size.
