Provided is a belt for electrophotography which is capable of suppressing the occurrence of adhesion to other members and blocking and which is less liable to cause image defects due to a singular protrusion. The belt for electrophotography comprises a surface layer which comprises heteroaggregate including an inorganic oxide particle having an average primary particle diameter of from 10 to 30 nm and an electroconductive metal oxide particle having an average primary particle diameter of from 5 to 40 nm, and a ten-point average roughness Rzjis of a surface of the surface layer satisfies a relationship: 0.3 μm≦Rzjis≦0.7 μm.
