An ink-jet recording head wherein thermal energy and an electroelastic field are applied to ink held between two plate members to cause the ink to be jetted out from an orifice defined by the plate members wherein there is provided, on the orifice-side end portion of each of the plate members adjacent the orifice, a first area readily wettable by the ink and a second area away from the orifice which is less wettable by the ink.

A thermal electrostatic ink-jet recording apparatus includes an orifice for storing and jetting ink. The orifice is formed between first and second plate members and a longitudinal array of heating elements is formed on one of the plate members and is covered by an insulating layer. An electrically conductive layer is formed either on the insulating layer or the other plate member and cooperates with a counter electrode supporting a recording medium to apply an electrostatic field to ink in the orifice. The electrically conductive layer includes a central portion that extends substantially to the egress of the orifice in the area where ink is contained in the orifice and peripheral portions on either side of the orifice that are not in contact with the ink and that are spaced substantially away from the egress of the orifice. The spacing of the peripheral portion away from the egress of the orifice prevents a gas discharge phenomenon that induces instability in ink jetting.

An ink transfer medium, and a method for manufacturing the medium are provided. The ink transfer medium is of the electrically fusible type, and has an anisotropically electrically conductive layer characterized by greater electrical conductivity in the direction normal to the surface of the layer than in a direction parallel to the surface of the layer. Other layers sequentially provided next to each other, include a resistive layer for converting an electrical signal into heat, a conductive layer, an ink separation layer, and a fusible ink layer. Examples are given illustrating the use of the ink transfer medium. The anisotropically electrically conductive layer may be made by anodizing an aluminum cylinder to form an alumina body defining a plurality of through-pores and electrolytically filling the through-pores with a metal such as nickel or cobalt.
摘要:
A printing head comprising a thin resin board, printing electrodes positioned in parallel with each other mounted thereon, projections of an electroconductive substance on the electrodes, and slits cut in the head between the projections, extending from the front edge of the resin board to a point midway between the front and rear edges of the resin board. An electrically insulating layer may be deposited on the surface of the head, leaving the projections clear. The thin elastic resin board can deform easily to comply to deformations and irregularities in the printing medium surface. The slits allow removal of foreign matter, such as dust. The slits further allow the electrode projections to contact the printing medium singly or in small groups, across the length of the printing head, rather than all at once, so that the presence of foreign matter on one electrode will not prevent any other electrode projection from making contact. Adequate reliable contact of the electrodes may be maintained to produce high print quality at a reduced stylus pressure, thereby decreasing wear and required maintenance on the printer head and extending its service life.
