PROBLEM TO BE SOLVED: To provide an ink-jet recording device having a liquid absorption member which suppresses image flow and has a high conveyance strength.SOLUTION: An ink-jet recording device includes an image formation unit which forms a first image containing a first liquid and a coloring material onto a body to be recorded, and a liquid absorption member having a porous body which has a first surface in contact with the first image and absorbs at least a part of the first liquid from the first image, where the porous body is a porous sheet formed by laminating a first layer 21 in contact with the first image, a second layer 41 containing a second fiber 44 and a third layer 31 containing a third fiber 32 in this order, an average fiber diameter of the second fiber is larger than an average fiber diameter of the third fiber, the second fiber has a core-sheath structure, a softening temperature of a material of the sheath structure is lower than any one of a softening temperature of a material of the core structure, a softening temperature of a material of the first layer and a softening temperature of a material of the third fiber, and an average thickness of the sheath structure is smaller than a thickness of the first layer.SELECTED DRAWING: Figure 6 【課題】画像流れが抑制され、高い搬送強度を有する液吸収部材を備えるインクジェット記録装置を提供する。【解決手段】被記録体上に第一の液体と色材とを含む第一の画像を形成する画像形成ユニットと、第一の画像と接触し、第一の画像から第一の液体の少なくとも一部を吸収する多孔質体を有する液吸収部材と、を備えるインクジェット記録装置であって、多孔質体が、第一の画像と接触する第一の層２１と、第二の繊維４４を含む第二の層４１と、第三の繊維３２を含む第三の層３１とがこの順で積層された多孔質シートであり、第二の繊維の平均繊維径が第三の繊維の平均繊維径よりも大きく、第二の繊維が芯鞘構造を有しており、鞘構造の材料の軟化温度が芯構造の材料の軟化温度、第一の層の材料の軟化温度及び第三の繊維の材料の軟化温度のいずれよりも低く、鞘構造の平均厚みが第一の層の厚みよりも小さい。【選択図】図６
