PURPOSE: To allow a sensitive body to withstand repeated use over a long period by incorporating a specified enamine compd. as an electric charge transferring agent into the photosensitive layer formed on the electrically conductive support.

CONSTITUTION: A sensitive body having superior sensitivity and durability is obtd. by using an enamine compd. represented by formula I in an electric charge transferring layer. In formula I, each of R1WR5 is optionally substd. alkyl, aralkyl, aryl or an arom. heterocyclic residue, R1 and R2 may form a ring, one of R3 and R4 may be H and R5 may be H. A concrete example of the compd. represented by formula I is represented by formula I-1.
