PURPOSE:To obtain clear and densified images by specifying terms of physical properties for a support body. CONSTITUTION:A support body 1 is composed of a porous film base 3 made of biaxially oriented film which is made of thermoplastic resin containing inorganic pulverized powder and a reverse layer 4 made of thermoplastic resin film having coefficient of dynamic friction of 0.3-1.2, preferably of 0.5-1.1, which is laminated to the reverse side of the base 3. The reverse layer 4 is made in thickness of 0.3-2.0mum, preferably of 0.5-1.5mum, and the support body 1 is made in physical properties that the opacity is 70% or more, preferably 80% or more, with density of 0.91g/cm<2> or below, preferably of 0.86g/cm<2> or below, and compressibility to stress of 32kg/cm<2> is 15-35%, preferably 20-30%. Thereby clear and densified images can be obtained. |
