Charging member, electrophotographic apparatus, and process cartridge

Abstract

Provided is a charging member capable of stably charging an object to be charged while suppressing adhesion of toner or an external additive onto a surface of an elastic layer and compression set of an abutting portion of the elastic layer. The charging member is a charging member, comprising a mandrel; and an electro-conductive elastic layer, wherein: the elastic layer has a universal hardness decreasing from a surface toward a depth direction thereof; and the hardnesses at a central portion and both end portions in a longitudinal direction of the charging member satisfy the relationships: in the surface of the elastic layer, the hardnesses at the both end portions are higher than that at the central portion; and at a position having a depth of t (μm) from the surface of the elastic layer, the hardness at the central portion is higher than those at the both end portions.
