Japanese Patent JP7434029

B2

To provide an electrophotographic belt that reduces the likelihood of the occurrence of unevenness in cleaning in a width direction performed by a cleaning blade even after a long-term use.SOLUTION: The electrophotographic belt is an endless electrophotographic belt and has a plurality of grooves in an outer peripheral surface. The plurality of grooves each extend in a circumferential direction of the electrophotographic belt. A groove formation area on the outer peripheral surface of the electrophotographic belt where the grooves are formed is divided into three areas by trisecting the overall width of the groove formation area in the width direction of the electrophotographic belt, and then the average value of the depths of the grooves included in the center area is determined as Dm, and the average values of the depths of the grooves included in areas on both ends are determined as De1 and De2, respectively, Dm, De1, and De2 satisfy the following formulas (1) and (2). (1) Dm
