(EN) An electrophotography photosensitive body hardly involving problems such as chartering and eversion of the cleaning blade and slide memory, a process cartridge having the electrophotography photosensitive body, and an electrophotograph are disclosed. The circumferential surface of the electrophotography photosensitive body has recesses of dimple shape. The ten point average height Rzjis (A) measured by scanning in the circumferential direction of the circumferential surface of the electrophotography photosensitive body is 0.3 to 2.5 μm, and the ten point average height Rzjis (B) measured by scanning in the direction of the generating line of the circumferential surface of the electrophotography photosensitive body is 0.3 to 2.5 μm. The average interval RSm (C) of the irregularities measured by scanning in the circumferential direction of the circumferential surface of the electrophotography photosensitive body is 5 to 120 μm, and the average interval RSm (D) of the irregularities measured by scanning in the direction of the generating line of the circumferential surface of the electrophotography photosensitive body is 5-120 μm. The ratio (D/C) of the average interval RSm (D) of the irregularities to the average interval RSm (C) of the irregularities is 0.5 to 1.5.(JA) クリーニングブレードのビビリやメクレの問題や摺擦メモリーの問題が発生しにくい電子写真感光体、ならびに、該電子写真感光体を有するプロセスカートリッジおよび電子写真装置を提供する。電子写真感光体の周面がディンプル形状の凹部を複数有し、電子写真感光体の周面の周方向に掃引して測定した十点平均粗さRzjis(A)が0.3~2.5μmであり、電子写真感光体の周面の母線方向に掃引して測定した十点平均粗さRzjis(B)が0.3~2.5μmであり、電子写真感光体の周面の周方向に掃引して測定した凹凸の平均間隔RSm(C)が5~120μmであり、電子写真感光体の周面の母線方向に掃引して測定した凹凸の平均間隔RSm(D)が5~120μmであり、凹凸の平均間隔RSm(D)の凹凸の平均間隔RSm(C)に対する比の値(D/C)が0.5~1.5である。
