PURPOSE: To obtain a lightweight drum-shaped image retaining body for electrostatic recording without requiring finish working by using an endless belt of a nonmagnetic metal having 0.1W2mm thickness manufactured by an electroforming method as a drum-shaped substrate and by forming an image retaining layer on the substrate.
CONSTITUTION: A drum-shaped substrate 21 is formed with an endless belt of a nonmagnetic metal such as Al manufactured by an electroforming method. Flange members 211, 211' are attached to the substrate 21 and set to a shaft member 24 with fixtures 212, 212'. Since the surface roughness of the substrate 21 is about 0.3 S, an undercoat layer is made unnecessary. The substrate 21 is coated with a photosensitive material such as zinc oxide to form an image retaining layer 22.
