Abstract
An electro-conductive roller, such as a charging roller, that can reduce abnormal electrical discharge in the axial direction of the roller and pinhole leak and be resistant to degradation in electrical characteristics even with long-term use, and a method of manufacturing the same, are provided. In an electro-conductive roller including fibers having electrical conductivity and arranged with no gap in the identical direction on the outer periphery surface of a mandrel, polymer fibers are adopted as the fibers.
