    • PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which is improved more in photosensitivity than in the conventional types.
      SOLUTION: The electrophotographic photoreceptor which includes a conductive substrate and a photosensitive layer, containing an anthraquinone derivative represented by general formula (1) is used. In general formula (1), R
      1 , R
      2 , R
      3 and R
      4 are the same or different from one another, and indicate a 6-18C substituted or unsubstituted aromatic monocyclic hydrocarbon group,and an aromatic polycyclic hydrocarbon group or a condensed polycyclic hydrocarbon group, comprisingat least one among a 1-8C substituted or unsubstituted alkyl group; a 7-18C substituted or unsubstituted aralkyl group; a 6-18C substituted or unsubstituted aryl group; a 3-12C substituted or unsubstituted cycloalkyl group; and a 1-8C substituted or unsubstituted alkoxy group.
