Abstract:
An electrophotographic photoreceptor belt which is excellent in durability and therefore little cracks even when fingerprints of an operator or hand cream adheres to the belt, wherein a binder resin for photosensitive layers comprising as the main component a polycarbonate resin which comprises bisphenol A type constituent units represented by the formula (I) as the main constituent unit (preferably in an amount of at least 90% by weight based on the whole of the constituent units) and which has a limiting viscosity of 1 to 1.6 dl/g and preferably a molecular weight distribution of 3.2 to 4.3 as calculated from the weight-average molecular weight and number-average molecular weight determined by GPC is used in a photosensitive layer (particularly carrier transport layer) of the belt.
