Abstract
In the present invention, a filler element 20 formed of a viscoelastic material with a compressive residual strain of 10% or less and a 25% compressive load of 1 kg/cm2, having a specific shape, is mounted in a drum-shaped electrophotographic photosensitive body (photosensitive drum) 10. The filler element 20 has a sufficient restoring force when deformed, so that it can be fixed to position without an adhesive. Also, the filler element 20 is not moved by vibration or shock during repeated use, and good anti-vibration effect can be maintained.
