    • PROBLEM TO BE SOLVED: To provide a support for an image recording material having both excellent smoothness and high glossiness, and an image recording material having high smoothness and high gloss, and giving clear image quality. SOLUTION: The support for an image recording material comprises base paper having a Cobb sizing degree of ≤25 g/m 2 and a smoothness (Oken system) of ≥200 s, and a porous coating layer formed from an aqueous foaming liquid and a covering forming polymer layer in this order on at least a surface of the base paper on which an image is formed. The image recording material using the support is also provided. The base paper preferably has a Cobb sizing degree of ≤20 g/m 2 and a smoothness of ≥250 s, a coating weight of the porous coating layer is preferably ≥10 g/m 2 , and the covering forming polymer layer is preferably formed by a dry process.
