Abstract
A semiconductive roller has an electrically conductive shaft, a roller provided on the shaft formed of silicone rubber with carbon contained therein. The silicone rubber is also added olefin oil and zinc oxide. A method is used for manufacturing a semiconductive roller formed of an electrically conductive shaft. The method includes carrying out a first vulcanization where the semiconductive roller is shaped into a roller and carrying out a second vulcanization where the semiconductive roller is heated at 200.degree. C. for substantially four hours.
