A porous body that includes a first porous layer including a first resin, a second porous layer including a second resin, and a third porous layer including a third resin in this order. The second porous layer has a portion where no material is present when viewed in a thickness direction.

Porous body, ink jet recording method, and ink jet recording apparatus

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 Tthrough Tof the first to third resins and heating temperature T in heating the first to third porous layers satisfy T&#x3c;T, T&#x3c;T, T&#x3c;T
