Claim:
1. An electroconductive member for electrophotography to be used while being brought into contact with a body to be contacted, the electroconductive member comprising: an electroconductive support; and a layer of a network structural body on an outer peripheral surface thereof, the network structural body comprising non-electroconductive fibers having an average fiber diameter of a top 10% of fiber diameters measured at arbitrary points of 0.2 to 15 μm, wherein when a surface of the electroconductive member is observed, at least a part of the network structural body exists in an arbitrary square region having one side length of 200 μm, and when a Voronoi tessellation is performed with generating points, the generating points being the non-electroconductive fibers exposed on a cross section in a thickness direction of the layer of the network structural body, areas of Voronoi polygons resulting from the Voronoi tessellation being defined as S1 and cross-sectional areas in the cross section of the non-electroconductive fibers as the generating points of the respective Voronoi polygons being defined as S2, when a ratio “S1/S2” is calculated an arithmetic average kU10 of a top 10% of the ratios is 40 to 160.
