    Abstract: An ink jet recording apparatus includes an orifice (5) for ejecting ink (6); a heater (4) for generating thermal energy to produce a bubble (8) to eject the ink; an ink passage (1) for supplying ink to the orifice (5), the ink passage being provided with the heater (4); an ink container (7) for containing ink to be supplied to the ink passage (1), the ink container retaining the ink, using capillary force; wherein the following is satisfied: VOH > V'Me + Vd where VOH is a volume of the ink passage (1) from the orifice (5) to an edge of the heater adjacent the orifice; V'Me is a volume of a meniscus retraction at an initial ink ejection; and Vd is a volume of ejected ink.

    Abstract: A length (c) of a melamine foamed block (12) to be accommodated in an ink tank housing (11) as measured in the longitudinal direction is dimensioned to be larger than a length (C) of the ink tank housing (11) as measured in the longitudinal direction. Thus, while the foamed block (12) is accommodated in the ink tank housing (11), it is compressed in the direction orienting toward an ink feeding port (13) from which ink is fed to a printing head (14), i.e., in the ink feeding direction. Consequently, the ink retaining force induced by the capillary force is not intensified in the compressing direction of the melamine foamed block (12), resulting in an ink feeding capability of the printing head (14) being improved. On the contrary, the ink retaining force effective at a right angle relative to the compressing direction of the melamine foamed block (12) is intensified.

    Abstract: An ink jet head having a plurality of heat generating resistive elements arranged in an array for discharging ink, comprises a base board having said heat generating resistive elements and a plurality of layers for electrical insulation or protection laminated on a substrate and liquid paths on said base board corresponding to said heat generating resistive elements. At least a part of said layers is removed between said heat generating resistive elements adjacent to each other.
