    Abstract: A method of reducing the kogation of the surface of the heater of a recording head for applying thermal energy to the ink in the recording head in order to discharge the ink from the recording head can effectively reduce the kogation to make it possible to print high quality images and prolong the service life of the recording head. With the method of reducing the kogation of the surface of the heater of the ink-jet recording head of an ink-jet printer, the ink-jet recording head is provided with a heater for applying thermal energy to ink in order to discharge ink from an orifice and the heater has a top surface protecting layer containing a metal and/or a metal oxide, while the ink is adapted to ink-jet recording and contains (a) a coloring material, (b) a liquid medium and (c) diglycollic acid or iminodiacetic acid or salts thereof.

    Abstract: The invention provides liquid compositions, ink sets for ink-jet recording, ink-jet recording processes, recording units and ink-jet recording apparatus for providing high-quality images with lessened bleeding. The invention also provides liquid compositions, ink sets for ink-jet recording, ink-jet recording processes, recording units and ink-jet recording apparatus for providing images excellent in water fastness. A first liquid containing a polyvalent metal salt of aldonic acid and a second liquid containing a coloring material capable of reacting with the polyvalent metal salt are used in combination and applied on a recording medium so as to come into contact with each other, thereby conducting recording.

    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.
