PURPOSE:To obtain an electrophotographic receptor or the like with high photosensitivity and superior durability, by adding a specified hydrazone compound as a photoconductor to a photosensitive layer, especially the charge transferring layer of a laminate type photosensitive layer on the charge generating layer. CONSTITUTION:To a photosensitive layer, especially the charge transferring layer of a separated function type laminated photosensitive layer is added a hydrazone compound represented by the formula where each of A and B is a (substituted) heterocyclic ring such as pyridine, carbazole, indole or benzoxazole, the substituent is alkyl, alkoxy, dialkylamino or the like, each of R1 and R2 is (substituted) alkyl, (substituted) aryl or (substituted) aralkyl, the substituent is alkyl, halogen or the like, and each of m and n is 0 or 1 , and the charge transferring layer is formed on the charge generating layer formed on an electrically conductive support. Thus, an electrophotographic receptor or the like with high photosensitivity and superior durability is obtd. |
