Abstract:
1. A process for producing a charging member comprising an electro-conductive support and an elastic layer as a surface layer, the elastic layer being formed by irradiating an outer peripheral surface of a vulcanized rubber layer with an electron ray, the elastic layer being a single layer and a sole layer, and having a cured region resulting from the irradiation with the electron ray only at an outer peripheral surface portion thereof, wherein the cured region has a hardness higher than a hardness of an interior portion of the elastic layer, and the cured region supporting spherical polyethylene particles in such a state that the spherical polyethylene particles are exposed to an outer peripheral surface of the charging member, and the outer peripheral surface of the charging member being thereby roughened; the process comprising the steps of: (1) forming the vulcanized rubber layer on an outer peripheral surface of the electro-conductive support, the vulcanized rubber layer containing the spherical polyethylene particles; (2) sanding the outer peripheral surface of the vulcanized rubber layer to make part of the spherical polyethylene particles exposed to the outer peripheral surface of the vulcanized rubber layer; and (3) irradiating with the electron ray the outer peripheral surface of the vulcanized rubber layer to which part of the spherical polyethylene particles stand exposed, obtained by the step (2), to form at the outer peripheral surface of the vulcanized rubber layer the cured region.
