摘要:
An electrophotographic photosensitive member is characterized by comprising a charge generation layer containing at least one disazo pigment represented by the following formula [I] and a charge transport layer containing at least one hydrazone compound represented by the following formula [II]: ##STR1## wherein A is a coupler residue, B represents hydrogen, halogen, alkyl, or alkoxy, and n is an integer of 1 to 4; ##STR2## wherein R.sub.1 represents N,N-dialkyl amino, or N,N-diarylamino, or N-alkyl-N-arylamino, or alkoxy or aryloxy, each being substituted or unsubstituted; R.sub.2 and R.sub.3 each represent alkyl, aralkyl, or aryl, each being substituted or unsubstituted, or R.sub.2 and R.sub.3, together with the nitrogen atom which links them, represent nitrogen-containing heterocyclic ring; R.sub.4 represents hydrogen, or alkyl, aralkyl, or aryl, each being substituted or unsubstituted; R.sub.5 represents hydrogen, alkyl, or alkoxy; and l is 0 or 1.
