Abstract
A method for producing a porous body for use in an ink jet recording apparatus including an image forming unit configured to form a first image including a first liquid and a coloring material on an ink receiving medium, and a liquid absorbing member including the porous body that contacts with the first image to absorb part of the first liquid from the first image. The method includes laminating a first porous layer that contacts with the first image and includes a first resin, and a second and a third porous layer including a second and a third resin; and heating the laminated first to third porous layers, wherein the second porous layer has a void when viewed in a thickness direction, and softening temperatures T1 through T3 of the first to third resins and heating temperature T in heating the first to third porous layers satisfy T2<T, T<T1, T<T3.
