A photosensitive member for electrophotography comprising at least a photoconductive layer on a conductive substrate, the photoconductive layer containing polyvinyl acetal having a constituent unit represented by the following general formula [I]: ##STR1## wherein Ar represents an aryl group, R.sub.1 a hydrogen atom, a lower alkyl group or an arly group, and m an integer of 0 or 1-3, and a constituent unit represented by the following general formula [II]: ##STR2## wherein R.sub.2 represents a hydrogen atom or an acyl group, the constituent unit of the general formula [I] being 40 mole % or more, and the total of the constituent units of the general formulae [I] and [II] being 60 mole % or more. This photosensitive layer has high sensitivity and durability and low residual potential.
A photosensitive member for electrophotography comprising at least a photoconductive layer on a conductive substrate, said photoconductive layer containing an organic photoconductive compound and a binder polymer, and said binder polymer comprising polyvinyl acetal having a repeating unit represented by the following general formula [I]:
