ABSTRACT:
A conductive roll including a conductive shaft, a conductive rubber foam layer formed on an outer circumferential surface of the conductive shaft, and a semi-conductive solid rubber layer formed on an outer circumferential surface of the conductive rubber foam layer. The conductive roll is produced by forming a cylindrical laminar body which gives the conductive rubber foam layer and semi-conductive solid rubber layer, and simultaneously vulcanizing and foaming the laminar body in a mold in which the conductive shaft is placed in position.
