To provide a method for manufacturing a porous body which suppresses an image flow and can be used for an inkjet recording device including a liquid absorption member having a high transportation strength.SOLUTION: There is provided a method for manufacturing a porous body in an inkjet recording device including: an image formation unit which forms a first image including a first liquid and a color material on a recorded body; and a liquid absorption member having a porous body which comes in contact with the first image and absorbs at least a part of the first liquid from the first image. The method includes: a step of laminating a first porous layer 110 coming in contact with the first image and including a first resin, a second porous layer 111 including a second resin and a third porous layer 112 including a third resin; and a step of heating the first to third laminated porous layers, where the second porous layer has a gap when being projected in a thickness direction, and softening temperatures T1 to T3 of the first to third resins and a temperature T heating the first to third porous layers satisfy T2<T, T<T1 and T<T3.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に用いることができる多孔質体の製造方法を提供する。【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における多孔質体の製造方法である。そして、第一の画像と接触し第一の樹脂を含む第一の多孔質層１１０と、第二の樹脂を含む第二の多孔質層１１１と、第三の樹脂を含む第三の多孔質層１１２とを積層する工程と、積層された第一から第三の多孔質層を加熱する工程とを有し、第二の多孔質層は厚み方向に投影した時に空隙を有し、第一から第三の樹脂の軟化温度Ｔ１〜Ｔ３と、第一から第三の多孔質層を加熱する温度ＴとがＴ２＜Ｔ、Ｔ＜Ｔ１かつＴ＜Ｔ３を満たす。【選択図】図６
