摘要

An image bearing drum having a hollow cylinder sleeve member; a photosensitive layer; a protective layer having fillers; and flange members, each of which has an attachment unit, a shaft hole unit, and a linking unit, wherein the surface of the protective layer having waviness has an arithmetical mean deviation of an assessed profile Wa (μm) of from 0.050μm to 0.400μm and a mean width of profile elements WSm (mm) of from 0.500 mm to 1.500 mm, and wherein the linking unit has at least one shock-absorbing hole located on a virtual line segment drawn to the shaft hole unit from the circumference of a virtually projected circle formed by projecting the outer periphery of the attachment unit axially along the shaft onto a virtual plane that contains the linking unit and is orthogonal to the shaft direction.
