    摘要： A liquid-drop discharge device is provided including a float cell provided with a valve and communicating to a liquid storage tank, a liquid discharge mechanism for discharging liquid within the float cell, and a reaction cell provided with a space into which fluid is discharged from the liquid discharge mechanism for collecting the discharged fluid. Air is supplied to the reaction cell for collecting liquid or minute particles, and an internal pressure P1 of the liquid storage tank or the float cell and an internal pressure P3 of the reaction cell are set such that a relationship of P1=P3, in which the pressures are identical to atmospheric pressure, or P1>P3, to supply stronger air, is satisfied.

    摘要： A recording head including an electrically insulating layer, a plurality of recording electrodes and at least one return circuit electrode provided on the opposite sides of the insulating layer, the insulating layer and electrodes being adapted to be held, at a distal end of the head, in contact with the resistive layer. The electrically insulating layer has a surface waviness represented by maximum filtered waviness, of not larger than 0.40 .mu.m, where a high band cut-off value is 0.8 mm and a reference length is 2.5 mm, as measured in main scanning direction perpendicular to a stacking direction of the electrically insulating layer, the recording and return circuit electrodes. The insulating layer also has a surface roughness represented by center-line mean roughness, within a range of 0.02 .mu.m to 0.4 .mu.m, where a cut-off value is 0.8 mm and a measuring length is 2.5 mm, as measured in the main scanning direction.
