Abstract
It is intended to provide a member for electrophotography that can inhibit the adhesion of dirt to the outer surface. The member for electrophotography has a substrate, an elastic layer on the substrate, and a surface layer on the elastic layer. The surface layer contains a binder resin and first particles, the surface of the surface layer has first convexes derived from the first particles, the first particles resulting in the first convex has an average inter-particle surface distance of 50 nm or less, the first particles have a number-average particle diameter of 200 nm or more and 1000 nm or less, and the surface of the surface layer has a universal hardness of 1.0 N/mmor more and 7.0 N/mmor less.
