    • The inkjet recording method includes: a treatment liquid depositing step of applying treatment liquid onto a recording medium while holding the recording medium on a circumferential surface of a treatment liquid drum and conveying the recording medium by rotating the treatment liquid drum, and drying at least a portion of a solvent in the treatment liquid; an image forming step of ejecting ink from a line type inkjet head to deposit the ink onto the recording medium on which the treatment liquid has been deposited, while holding the recording medium on a circumferential surface of an image formation drum and conveying the recording medium by rotating the image formation drum, the ink containing at least a resin dispersant (A), a pigment (B) that is dispersed by the resin dispersant (A), self-dispersible polymer micro-particles (C) and an aqueous liquid medium (D), the ink having one of a solid component that is aggregated upon making contact with the treatment liquid and a solid component that is precipitated upon making contact with the treatment liquid; and a drying step of drying a solvent in the ink having been deposited on the recording medium while holding the recording medium on a circumferential surface of a drying drum and conveying the recording medium by rotating the drying drum.
    • 喷墨记录方法包括:处理液体沉积步骤,其将处理液体保持在记录介质上,同时将记录介质保持在处理液体滚筒的圆周表面上,并通过旋转处理液体滚筒输送记录介质,并干燥至少一个 处理液中溶剂的一部分; 图像形成步骤,从线型喷墨头喷射墨水,以将油墨沉积到已经沉积有处理液体的记录介质上,同时将记录介质保持在图像形成鼓的圆周表面上并通过以下方式传送记录介质 旋转图像形成鼓,含有至少一种树脂分散剂(A)的油墨,由树脂分散剂(A)分散的颜料(B),自分散性聚合物微粒(C)和水性液体介质 D),具有与处理液接触时聚集的固体成分和与处理液接触而析出的固体成分之一的油墨; 以及干燥步骤,其将已经沉积在记录介质上的油墨中的溶剂干燥,同时将记录介质保持在干燥鼓的圆周表面上,并通过旋转干燥鼓来输送记录介质。
