Abstract
A photosensitive member for electrophotography has a photosensitive layer provided on a photoconductive substrate. The photosensitive layer contains at least one of indole derivatives represented by a chemical formula (I): ##STR1## wherein R.sub.1 and R.sub.2 are members selected from a group consisting of hydrogen atom and alkyl, aralkyl, allyl and alkoxy groups having 1-9 carbon atoms (but R.sub.1 and R.sub.2 do not stand for hydrogen atoms at the same time); R.sub.3 is a member selected from a group consisting of hydrogen and halogen atoms and alkyl and alkoxy groups having 1-3 carbon atoms; X is a member selected from a group consisting of alkylen, allylen, carbonyl, sulfonyl, sulfinyl and sulfide groups and oxygen atom; and n stands for an integer of 0 or 1.
