Abstract
An inventive semiconductive roller includes a tubular semiconductive rubber layer () rotatable in a rotation direction, the semiconductive rubber layer having a multiplicity of minute projections () provided in circumferentially and axially discrete relation on an outer peripheral surface () thereof, the minute projections each having an apex () located forward (F) in the rotation direction and two edges () extending from the apex rearward (R) in the rotation direction obliquely with respect to the rotation direction so that the projections are each flared with a width (w) thereof progressively increasing in a rearward direction (R) from the apex () as measured axially of the semiconductive roller.
