摘要： A photosensitive member for electrophotography comprising a photosensitive layer on a conductive substrate, said photosensitive layer containing as a binder resin a modified polycarbonate resin having the repeating structural units represented by the following general formula (1) and (2); ##STR1## wherein R.sup.1 and R.sup.2 are selected from a hydrogen atom, an alkyl group having 1-3 carbon atoms and a halogen atom, at least one of R.sup.1 and R.sup.2 being the alkyl or the halogen atom, and ##STR2## the ratio of the repeating structural unit of the general formula (1) to that of the general formula (2) being at least 20:80. This photosensitive member is highly resistant to mechanical wear and the deterioration of sensitivity and chargeability.
