PURPOSE:To obtain a photosensitive body good in sensitivity even in the case of repeated uses and improved in drop of surface potential and rise of residual potential by incorporating a specified electric charge transfer material and a specified electron acceptor. CONSTITUTION:The photosensitive body contains at least an aryl-amine compound and the electron acceptor having an electron affinity of 0.85-1.0eV on a conductive substrate. The arylamine compound to be used functions as the charge transfer material and it is represented by formula I in which each of Ar1-Ar4 is optionally substituted aryl, aralkyl, biphenyl, or a heterocyclic group; each of Ar5 and Ar6 is an optionally substituted aryl, biphenyl, or fluorenyl group; X is -O-, -S-, -NR1-, or -CR2R3-; R1 is H, alkyl, aralkyl, or a heterocyclic group: each of R2 and R3 is H or aryl; and (n) is 0 or 1.
