Photosensitive drum and vibration reduction method for same, and photosensitive drum unit

摘要

Disclosed is a photosensitive drum that is provided with a structure that can decrease noise-causing vibrations without being accompanied by the addition of new parts. The photosensitive drum (2) is provided with a tube-shaped conductive base (11) on the surface of which a photosensitive layer (12) is formed, and flanges (13) attached to both ends of the conductive base (11) by being inserted into said both ends. The end sections (13a) of the flanges (13) in the tube-length direction (Z) of the conductive base (11) contact the inner surface (11a) of the conductive base (11) within an electrically-charged region (Le) of the photosensitive layer (12).

主权项

1. A photosensitive drum unit, comprising:
a photosensitive drum having a tube-shaped conductive base with a surface on which a photosensitive layer is formed, and a flange inserted from an end of said conductive base and attached to the end; and an electrifier for electrically charging the photosensitive layer, wherein the flange is in contact with an inner surface of the conductive base within a contact region between the photosensitive layer formed on the surface of the conductive base and said electrifier.
