Claim:
1. An electrophotographic member comprising: an electro-conductive substrate; and an electro-conductive resin layer as a surface layer on the substrate, the electro-conductive resin layer comprising a binder and retaining a bowl-shaped resin particle having an opening that is exposed at a surface of the electrophotographic member; the surface of the electrophotographic member comprising a concavity derived from the opening of the bowl-shaped resin particle exposed at the surface, and a protrusion derived from an edge of the opening of the bowl-shaped resin particle exposed at the surface; and a part of the surface of the electrophotographic member is constituted by the electro-conductive resin layer, wherein a brightness observed at a bottom of the concavity K a brightness observed at an exposed surface of the electro-conductive resin layer K when the surface of the electrophotographic member is observed with a scanning electron microscope at an accelerating voltage of 1 kV and a magnification of ×2000 while applying a DC voltage of 50 to 100 V between an electrode disposed opposite to the electrophotographic member and the electro-conductive substrate.
