PURPOSE: To enable stable and easy manufacture of an electrophotographic sensitive body superior in electrifiability, potential stability, and light responsivity, and durable against repeated uses by using a mixture of solvents different in characteristics as the solvent of a specified butadiene derivative to be incorporated in the photosensitive layer of said photosensitive body.
CONSTITUTION: The electrophotographic sensitive body is provided on a conductive substrate with the photosensitive layer containing at least one of the butadiene derivatives represented by formula I in which each of R1WR4 is lower alkyl. The photosensitive layer is formed by using as the solvents for the coating solution of said butadiene derivative a mixture of one selected from a group A; ones causing drop of ≥60°C in the difference between the melting point of said derivative before dissolution and that after dissolution in said solvent and removal of it; and a group B dropping the melting point only by ≤20°C in said difference, thus permitting the photosensitive body superior in characteristics to be produced stably and industrially easily by the use of said solvent mixture.
