Semiconductive roller |
摘要 |
A semiconductive roller for use as a developing roller or the like is provided, which has an outer peripheral surface at least partly imparted with a reduced friction coefficient μ without irradiation with ultraviolet radiation. The semiconductive roller (1) includes a tubular body made of a crosslinking product of an electrically conductive rubber composition containing a crosslinkable rubber component, and a chloride film (5) formed in the outer peripheral surface (4) thereof through chlorination. |

1. A semiconductive roller comprising a tubular body made of a crosslinking product of an electrically conductive rubber composition containing a crosslinkable rubber component, and having a chlorinated outer peripheral surface,
wherein the outer peripheral surface has a friction coefficient μ of not greater than 0.15, and wherein the rubber component includes an ethylene propylene diene rubber in a proportion of not less than 30 parts by mass and not greater than 70 parts by mass based on 100 parts by mass of the overall rubber component. |
