Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a conductive roll for electrophotographic equipment, in which adhesion failure of a rubber elastic material layer to a shaft can be suppressed as an adhesive having a long pot life is used, and adhesion strength is improved compared to a conventional roll using a one-component epoxy adhesive.SOLUTION: The conductive roll includes a shaft 12, an adhesive layer 14 formed on an outer circumferential surface of the shaft 12, and a rubber elastic material layer 16 formed on an outer circumferential surface of the adhesive layer 14. The rubber elastic material layer 16 is formed by using an addition reaction type silicone rubber; and the adhesive layer 14 is formed by using (A) a one-component epoxy adhesive and (B) a compound having a functional group reactive with an alkenyl group or a hydrosilyl group.
