Abstract
A semiconductive roller to stably generate high-quality images for a long period of time by efficiently inhibiting migration of free epichlorohydrin (ECH) component to a surface of the semiconductive roller includes an elastic layer formed of a semiconductive rubber composition including about 50 to about 70 parts by weight of a base rubber and about 30 to about 50 parts by weight of a hydrin rubber. An extracted amount of the ECH component from the elastic layer is about 2% by volume or less, wherein the extracted amount is determined based on a reduced amount of chlorine (Cl) intensity measured using X-ray fluorescence (XRF) analysis performed before and after extraction of the ECH component from the elastic layer using tetrahydrofuran (THF).
