Disclosed are an ink set comprising a recording composition and a treating composition which can produce a high quality image without feathering or color bleed on a plain paper, an image forming process and an image forming apparatus using the same, and a print. An image is formed by applying a recording composition containing a colorant and a treating composition containing a component reactive with the colorant so that they contact and be mixed on a recording medium and adjusting the pH of the mixture. In the image formation, the component has an isoelectric point where the zeta potential (ζ) is zero according to the pH change of the mixture and the compositions are adjusted so that the pH (a) at which the change ζ according to pH in the more acidic side from the pH (c) is −2.5 mV·l/mol satisfies a<γ and a
本发明公开了一种由记录组合物和处理组合物组成的油墨组,该油墨组可以在普通纸上产生没有羽化或渗色的高质量图像,还公开了使用该油墨组的图像形成工艺和图像形成设备,以及印刷品。通过在记录介质上使用含有着色剂的记录组合物和含有与着色剂反应的成分的处理组合物,使它们接触并混合,并调节混合物的 pH 值,从而形成图像。在图像形成过程中,组分具有等电点,根据混合物的 pH 值变化,等电点的 zeta 电位 (ζ)为零,调整组合物使 pH 值 (a) 满足 a<γ 和 a
