Abstract
This invention provides an improved electrifying member capable of that can have an electric voltage applied to it to electrify a surface of another member which is to be electrified. In particular, said electrifying member comprises an electrically conductive elastomer obtained by vulcanizing a mixture containing a nitryl rubber, a liquid nitryl rubber, and a non-polar polymer. Therefore, the invention provides an improved electrophotograph apparatus employing the above improved electrifying member, which has a relatively uniform electric resistance and uniform electrifying characteristics, has almost no change in its characteristics even if it has been used for a long time period, and is non-viscous and thus will not stick to a photosensitive body (to be electrified) so that it will not contaminate the photosensitive body.
