    • PURPOSE: A recording unit, an image recording device and an image recording method are provided to make black images and characters formed by a black ink in the presence of a color ink satisfy various functions as a high optical density, high image quality and high image fastness, to prevent bleeding and white haze and to reduce the consumption of the ink. CONSTITUTION: An ink jet head(H1001) employing an ink set including black 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. At least one of the color inks contains a polyvalent metal salt, which impairs the dispersion stability of the coloring material in the black ink, in being mixed with the black ink. 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 bubbles generated in the ink in an ink flow path(H1501) are opened through to a discharge port at the ink discharge.
    • 目的:提供一种记录单元,图像记录装置和图像记录方法,用于在彩色墨水的存在下由黑色墨水形成的黑色图像和字符满足各种功能,作为高光密度,高图像质量和高图像 坚牢度,防止出血和白霾,并减少墨水的消耗。 构成:使用包含黑色和彩色油墨的油墨组的喷墨头(H1001),其中黑色油墨含有盐,水性介质和通过离子基团的功能分散在水性介质中的着色材料。 至少一种彩色油墨含有多种金属盐,其与黑色油墨混合会损害黑色油墨中着色材料的分散稳定性。 喷墨头具有用于排出含有用作彩色油墨的油墨的多价金属盐的部分的结构,利用其中在油墨流路(H1501)中的油墨中产生的气泡通过排出口 在墨水排出。

    • PURPOSE: A liquid ejection head and an image forming device using the liquid ejection head are provided to remove white streaks generated in a solid printing by restricting the deviation of liquid drops ejected from ejection openings which are arranged at a respective opposite end section along an arranged direction. CONSTITUTION: A liquid ejection head includes a plurality of ejection openings arranged in a first direction and a plurality of electro-thermal transducers for ejecting liquid from the ejection openings. The liquid ejection head and a printing medium perform the relative movement, wherein an arrangement pitch(d1) of ejection openings(25e) forming an end group located in a respective opposite end section along the first direction is longer than an arrangement pitch(d0) of ejection openings(25c) forming a central group located in the central section along the first direction with 0.1¯10 micron m.
    • 目的:提供使用液体喷射头的液体喷射头和图像形成装置,以通过限制从设置在相应的相对端部处的喷射口喷射的液滴的偏离沿着布置的位置来去除在固体印刷中产生的白色条纹 方向。 构成:液体喷射头包括沿第一方向布置的多个喷射口和多个用于从喷射口喷射液体的电热换能器。 液体喷射头和打印介质进行相对运动,其中沿着第一方向形成在相应的相对端部中的端部组的喷射口(25e)的排列间距(d1)比排列间距(d0)长, 的喷射口(25c),其形成沿着第一方向位于中心部分的中心部分,具有0.1〜10微米的m。
