PURPOSE:To obtain a roller electrifier of good electrifying capacity where partial unevenness and variance of the surface resistance are small, by providing a conductive layer on the surface of an electrode roller and providing an elastic body layer on the inside. CONSTITUTION:With respect to the roller electrifier which electrifies a member 2 to be electrified by an electrode roll 1 which is rotated while being brought into contact with the surface of the member 2, a conductive layer 13 is provided on the surface of the electrode roll 1, which is the contacting surface between the electrode roll 1 and the member 2 to be electrified, and an elastic body layer 12 is provided on the inside to constitute the electrode roller 1 of at least two-layered structure. Thus, the unevenness and the variance of conductivity are reduced, and the hardness of the roll is controlled by the elastic body layer 12 to obtain the electrode roll of optional hardness, and the roller electrifier which has a stable nip width and uniformly electrifies the member is obtained. |
