<p>In a head of an electroosmotic ink recording apparatus wherein a porous substance film 40 and a second electrode 50 which is permeable to a fluid ink 200 are accumulated in sequence on a principal face 11 of a non-porous substrate 10, on which a plural number of first electrodes (recording electrodes) 20 are provided, signal voltages V<Sub>e</Sub> and V<Sub>B</Sub>' for ink recording being applied between the first electrodes 20 and the second electrode 50,</p><p>the first electrodes are of ink-philic conductive substances and their surfaces are isolated with a substantially ink-repellant and insulative substance, thereby recording has a clear discretion between neighboring dots drawn by corresponding neighboring seconds electrodes.</p> |
