PROBLEM TO BE SOLVED: To provide a conductive roll for an electrophotographic apparatus, which has a conductive rubber elastic layer that has a lower hardness and a smaller compression set compared to conventional products.SOLUTION: A conductive roll 10 for an electrophotographic apparatus includes a shaft 12 and a conductive rubber elastic layer 14 disposed on an outer circumference of the shaft 12. The conductive rubber elastic layer 14 comprises a polar rubber, a nonpolar rubber and a dispersant. The polar rubber is at least one of nitrile rubber, hydrin rubber and chloroprene rubber. The nonpolar rubber is at least one of isoprene rubber, hydrogenated isoprene rubber and natural rubber. The dispersant is at least one of a polymer having a block made of a nitrile rubber component and a block made of an isoprene rubber component, modified natural rubber and modified isoprene rubber.SELECTED DRAWING: Figure 1 |
