PURPOSE:To enhance sensitivity and durability by incorporating a polymer of alkyleneimine substituted by a specified carbazole derivative in an electric charge transfer layer. CONSTITUTION:The charge transfer layer contains at least one of the polymers of alkyleneimines substituted by the carbazole derivatives represented by formula I in which A is a divalent aliphatic or aromatic >=2C group optionally containing oxygen; each of R1 and R2 is H, halogen, optionally substituted straight or branched alkyl or the like, optionally same or different from each other; each of R3 and R4 is optionally substituted straight or branched alkyl, optionally substituted aralkyl, or the like, optionally same or different from each other; (n) is an integer of >=2; and (m) is an integer of 2-20, thus permitting sensitivity and durability to be both enhanced. |
