titleOfInvention | Recording unit, image recording apparatus and image recording method |
abstract | The invention provides a recording unit and an image recording apparatus of a configuration in which the black image and character formed by the black ink in the presence of the color ink satisfy various properties such as a high optical density, high image quality and high image fastness and which also enables prevention of bleeding and white haze and saving of the ink consumption. n There is provided an ink jet head employing an ink set including black ink and color inks, in which the black ink contains a salt, an aqueous medium and a coloring material dispersed in the aqueous medium by the function of an ionic radical, and at least one of the color inks contains a polyvalent metal salt capable, when mixed with the black ink, of impairing the dispersion stability of the coloring material in the black ink, and the ink jet head has a configuration, in a portion for discharging the polyvalent metal salt containing ink used as the color ink, utilizing a discharge method in which the bubble generated in the ink in the ink flow path is opened through to the discharge port at the ink discharge. |
