Zusammenfassung:An electrophotographic belt having an endless shape, has grooves in an outer surface of the electrophotographic belt, and the grooves each are extending in a circumferential direction of the electrophotographic belt, wherein the outer surface has at least a first region in which the number of the grooves in a direction orthogonal to the circumferential direction of the electrophotographic belt is n, and a second region in which the number of the grooves in the direction orthogonal to the circumferential direction of the electrophotographic belt is more than n, and the grooves in the second region include a first groove that has a width gradually decreasing in a first circumferential direction of the electrophotographic belt, and a second groove that is adjacent to the first groove and has a width gradually decreasing in a second circumferential direction opposite to the first circumferential direction.
