ELECTROPHOTOGRAPHY PHOTOSENSITIVE BODY, METHOD FOR PRODUCING ELECTROPHOTOGRAPHY PHOTOSENSITIVE BODY, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPH

摘要

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 mum, 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 mum. 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 mum, 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 mum. 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.
