Abstract
A conductive member (10) includes a conductive supporting body (1), an electric resistance adjusting layer (2), which is formed onto the conductive supporting body (1) and is disposed to face a photoconductor (4), and a pair of space holding members (3, 3) disposed in both ends of the electric resistance adjusting layer (2), so as to have contact with the photoconductor (4) to maintain a predetermined gap (G) between the electric resistance adjusting layer (2) and the photoconductor, and each of the space holding members (3, 3) includes a cylinder portion (3a) attached to the outer circumference surface (2a) of the electric resistance adjusting layer and an end plate (3b) provided in one end portion of the cylinder portion and disposed to have contact with the end surface (2b) of the electric resistance adjusting layer.
