Abstract
To provide metallic paper that is excellent in adhesion to an image even when image formation is performed in an electrophotographic system.SOLUTION: Metallic paper for electrophotography contains polyester in its surface. The ratio of the following peak area B to the following peak area A (B / A) of an IR spectrum obtained by measuring the surface of the metallic paper by an ATR method (crystal: Ge, incident angle: 45°, single reflection) is 0.90 or less. [Peak] an area of the peak area A: 1709.586-1741.406 cm-1; an area of the peak area B: 1630.519-1670.052 cm-1; a base line: 1593.878-1850.364 cm-1.SELECTED DRAWING: Figure 1
