CONDUCTIVE ROLL

摘要

PROBLEM TO BE SOLVED: To provide a conductive roller having the both of good compressive permanent strain and formability and having no variation in an electric resistance value in a semiconductive region. SOLUTION: This conductive roll consists of an axial body 1 and three layers formed on the outer peripheral surface of the axial body 1. The innermost layer 2 among the three layers is formed from a polymer compsn. essentially consisting of an ethylene-propylene-diene copolymer polymerized by using a metallocene catalyst and the electric resistance value is set within 1×104 to 6×108Ω.cm.
