PURPOSE:To provide a subject head which is uniform in the size of a recording dot and improves a picture quality, by a method wherein, in order to uniformalize a dot to be recorded, a distance from a position of a discharge orifice to a discharge energy generating means is caused to varry with the location of a head. CONSTITUTION:A plurality of discharge orifices from a multiorifice array structure which is erected in a perpendicular direction to form a recording head. A distance D from a discharge orifice at the energy operating part of the recoding head to a heating resistor 11-i is caused to vary with the location of the head, or the distance D at the upper part of the head is caused to differ with that at the lower part of the head. If the distance D is set to a shorter one at the lower end of the head as compared with that at the upper part of the head, a difference in the size of the recording dot can be almost disregarded. |
