Beschreibung
Zusammenfassung:	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 VB and VB' for ink recording being applied between the first electrodes 20 and the second electrode 50, the first electrodes are of ink-philic (generally hydrophilic) conductive substance and their surfaces are isolated with a substantially ink-repellant (generally hydrophobic) and insulative substance, thereby recording has a clear discretion between neighboring dots drawn by corresponding neighboring second electrodes.
