Abstract: Disclosed herein is a liquid discharging method, comprising using a liquid-discharge head equipped with a discharge opening from which a liquid is discharged, a first region to which a first liquid is supplied, a bubble-generating region containing a second liquid and generating bubbles in the second liquid, and a movable member which is displaceable between a first position opposite to the bubble-generating region and a second position within the first region and apart from the bubble-generating region and has a support part more upstream than its free end, in which the movable member is displaced from the first position toward the second position with the generation of a bubble in the bubble-generating region, and the bubble is guided to the discharge opening by the movable member, wherein the first liquid and the second liquid have no compatibility with each other.

Abstract: An aqueous ink comprising at least water, a water-soluble organic solvent and a colorant. The colorant comprises a pigment containing a pigment particle having at least one ionic group bonded to a surface of the pigment particle directly or via another atomic group. The organic solvent undergoes completely or substantially no solvation with the pigment and the ionic group of the pigment particle undergoes completely or substantially no ion dissociation in the organic solvent.

Abstract: Disclosed is an aqueous ink comprising at least water, a plurality of water-soluble organic solvents and a coloring material. The coloring material is a pigment, and, it contains a pigment particle having at least one ionic group bonded to a surface of the pigment particle directly or via another atomic group. The plurality of water-soluble organic solvents have a good medium or good mediums for the pigment and a poor medium or poor mediums for the pigment. The poor medium does not solvate perfectly or substantially the pigment. The ionic group undergoes perfectly or substantially no ionic dissociation in the poor medium. Also, among the respective Ka values of the plurality of water-soluble organic solvents as determined by the Bristow method, the Ka value of the poor medium is maximum.

Abstract: An ink jet recording method and apparatus for performing recording by discharging ink onto a recording medium in accordance with recording data using a recording head having ink discharge ports for discharging the ink. The apparatus includes a scanning unit for scanning the recording head relative to the recording medium for discharging ink to record pixels on the recording medium, and a determining unit for determining whether the recording data includes non-discharge data for a predetermined number of successive pixels to be recorded by the recording head, and for generating a corresponding determination output signal. The apparatus further includes a control unit for controlling ink discharge in accordance with the determination output signal such that an amount of ink discharged for forming at least one pixel subsequent to the predetermined number of successive pixels is reduced from a predetermined recording amount, when the recording data is determined to include non-discharge data for the predetermined number of successive pixels.
