Claim:
1. An electroconductive member for electrophotography comprising: an electroconductive support layer; and a surface layer thereon, wherein: the surface layer has a network structure containing fibers, the fibers having an arithmetic mean value d the electroconductive support layer has a rigid structural body, and in a cross section in a thickness direction of the electroconductive member, the rigid structural body having a height of 1.0×10 wherein: the surface layer satisfies the following (1) to (3): (1) when the surface layer is observed in such a manner as to face the surface layer, one or more crossings of the fibers are observed in a square region having one side length of 1.0 mm on a surface of the surface layer; (2) when the surface layer is observed in such a manner as to face the surface layer, at least a part of the rigid structural body is observed in a square region having one side length of 1.0 mm on the surface of the surface layer; and (3) when a Voronoi tessellation is performed with generating points, the generating points being the fibers exposed on a cross section in a thickness direction of the surface layer, wherein areas of Voronoi polygons resulting from the Voronoi tessellation is defined as S wherein cross-sectional areas in the cross section of the fibers as the generating points of the respective Voronoi polygons is defined as S an arithmetic mean value k
