1. A photoconductor drum comprising:
- a drum body that is cylindrical; and
a pair of flanges fitted to or near two axial ends of the drum body,wherein at least one of the flanges includes a plurality of engagement protrusions disposed on an inner circumferential surface of a through-hole for inserting a drive shaft for drivingly rotating the photoconductor drum, the through-hole having a larger radius than the drive shaft, andwherein, in each of the flanges, the engagement protrusions are disposed so as to correspond to a single position or a plurality of positions in an axial direction.

16. A rotatable body system comprising:
-
a rotatable body including at least two flanges; and a drive shaft for drivingly rotating the rotatable body, the drive shaft being inserted into a through-hole of the at least one flange, the through-hole having a larger radius than the drive shaft, wherein, each of the at least two flanges includes a plurality of engagement protrusions disposed between the through-hole and the drive shaft, and wherein, in each of the at least two flanges, the engagement protrusions are disposed so as to correspond to a single position or a plurality of positions in an axial direction.
