Zusammenfassung: | To provide a liquid absorption member which can suppress deformation of an ink image even if there is a portion with a low liquid permeable property in a porous body.SOLUTION: A liquid absorption member 105a includes a porous body 10 in which a plurality of porous layers are laminated. The porous body 10 includes a first surface 10a which absorbs liquid. Liquid permeates in the first direction crossing each porous layer from the first surface 10a. The liquid absorption member includes a blocking part 11 which blocks the flow of the liquid in the first direction in an i (2≤i≤N)-th porous layer when the layer number of the porous layers is N(>2) and the porous layer constituting the first surface 10a is a first porous layer, and includes a non-adhesive region 12 where a j (2≤j≤i)-th porous layer and a j-1-th porous layer do not adhere to each other in a region opposed to the blocking part 11 on an interface between the j-th porous layer and the j-1-th porous layer.SELECTED DRAWING: Figure 2
【課題】多孔質体中に透液特性の低い部分があっても、インク画像の変形を抑制することができる液吸収部材を提供する。【解決手段】複数の多孔質層を積層した多孔質体10を有し、該多孔質体10は液体を吸収する第1の面10aを備え、該第1の面10aから各多孔質層を横断する第1の方向に液体が浸透する液吸収部材105aであって、多孔質層の層数をN(>2)とし、第1の面10aを構成する多孔質層を第1番目の多孔質層とした場合に、第i(2≦i≦N)番目の多孔質層に第1の方向への液体の流れを遮る閉塞部11を有し、第j(2≦j≦i)番目の多孔質層と第j-1番目の多孔質層との界面の閉塞部11と対向する領域に、第j番目の多孔質層と第j-1番目の多孔質層とが互い接着しない非接着領域12を有する。【選択図】図2 |
