Claims

[Scope of utility model registration request]

In a photoconductor drum that is rotatable by fitting a flange section made of a non-conductor to both ends of a drum section made of a cylindrical conductor and pivoting the flange section to a photoconductor drum bearing shaft, at least one flange An elastic plate made of a conductor is attached to the inward facing surface of the part, and the elastic force of this elastic plate allows
Two or more divided drum contact parts on one end side of the elastic plate are brought into pressure contact with the inner peripheral surface of the drum part, and the bearing shaft contact part on the other end side is connected to the photoconductor drum bearing shaft which is grounded to the main body of the apparatus. A grounding structure for a photosensitive drum characterized by pressure contact.
