Abstract
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.
