PURPOSE:To enhance durability and cleanability, to improve potential acceptance and potential stability in the dark, to elevate sensitivity, to reduce residual potential, and to ameliorate repetition stability and environment stability by forming a protective layer made of a water-soluble or water-dispersible graft polymer composed of the trunk polymer of a polyester having hydrophilic groups and the branched polymers of acrylic polymers. CONSTITUTION:The protective layer is made of the water-soluble or water- dispersible graft polymer composed of the trunk polymer of a polyester having the hydrophilic groups, and the branched polymers of acrylic polymers, and it is formed by coating the surface of the photosensitive body with this graft copolymer, drying, and heat hardening the coating film, thus permitting the obtained photosensitive body to be superior in durability and cleanability, good in potential acceptance and stability in the dark, high in sensitivity, low in residual potential, and good in reception stability and environment stability. |
