A composite photographic pace having high rigidity, excellent smoothness, high opacity, and excellent moisture curl resistance, wherein the composite imaging element has fewer cutting defects during the cutting process. . An image forming member including an image forming layer and a base, wherein the base includes a closed cell foam core sheet (4) and an upper flange sheet (2) and a lower flange sheet (3) adhered thereto. The foam core sheet 4 has a modulus between 100 and 2758 MPa and a tensile toughness between 0.344 and 35 MPa, and the upper flange sheet 2 and the lower flange sheet 3 have a modulus between 1380 and 20000 MPa and It has a toughness between 4 and 210 MPa.
