PROBLEM TO BE SOLVED: To evade an impact in the vertical direction during transportation by projecting an elastically deformable core material inserted into a photoreceptor belt from its bottom end. SOLUTION: The elastically deformable core material 3 inserted into the photoreceptor belt is projected from its bottom end, so that the belt 1 is held to be hollow in a container 2 due to the restoring force of the core material 3. As the core material 3, a regular or irregular member capable of keeping the shape of the belt 1 a fixed shape such as a nearly cylindrical shape, for instance, when the core material 3 is inserted into the belt 1 and left standing and exerting the restoring force capable of restraining the belt 1 by the outer periphery of the core material 3, on the inside surface of the belt 1 can be used. Concretely, as the core material 3, a synthetic resin sheet 31 for fulfilling expansive force when the core material 3 is cylindrically wound can be used. In the synthetic resin sheet 31, a synthetic resin film, a rubber sheet, etc., are included. |
