摘要： Provided is an electrophotographic belt sustainably excellent in toner removal performance. The electrophotographic belt has an endless shape and has grooves on an outer surface thereof, each of the grooves extending in a circumferential direction and being in non-parallel with the circumferential direction, and the outer surface is composed only of a first region in which the number of the grooves in a direction orthogonal to the circumferential direction is “n” and a second region in which the number of the grooves in the direction orthogonal to the circumferential direction is larger than the “n”, the first region and the second region being arranged alternately in the circumferential direction, and the “n” being an integer of 1 or more.

摘要： A resin product including an antireflection surface includes a plurality of first concave portions, a plurality of second concave portions, and a component surface. The first concave portions have opening widths equal to or larger than 1 μm and equal to or smaller than 300 μm. The second concave portions are formed on each of the plurality of first concave portions and have opening widths equal to or larger than 10 nm and equal to or smaller than 1 μm. The component surface is configured to surround each of the plurality of first concave portions.
