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 0.3-2.0μm, preferably of 0.5-1.5μm, 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/cm2 or below, preferably of 0.86g/cm2 or below, and compressibility to stress of 32kg/cm2 is 15-35%, preferably 20-30%. Thereby clear and densified images can be obtained.
