Abstract
Provided is a charging member which hardly causes a cleaning failure in a photosensitive member while having such flexibility that a sufficient nip width can be formed with respect to a photosensitive member. The charging member comprises: an electro-conductive support; and an elastic layer as a surface layer, wherein: the elastic layer has a hardened region formed by irradiation with an electron beam; and the hardened region supports a composite particle in a state in which the composite particle is exposed on the surface of the elastic layer, thereby roughening the surface of the elastic layer, and wherein: said composite particle includes a silica-containing porous particle whose surface is coated with a carbon-containing film.
