Electrophotosensitive material and method of producing the same

An electrophotosensitive material comprising a supporting substrate, an intermediate layer containing a thermosetting resin formed on the supporting substrate, and a photosensitive layer formed on the intermediate layer,

• wherein a contact angle of the surface of the intermediate layer is not less than a value (A°) represented by the formula:
• A°=B°−2° in which B° is a contact angle corresponding to an intersection of a first approximation linear line and a second approximate linear line in a correlation curve between a residual potential of the photosensitive material comprising the predetermined photosensitive layer formed on the intermediate layer containing the thermosetting resin and a contact angle of the intermediate layer containing the thermosetting resin;
• wherein the first approximate linear line denotes an approximate linear line of the portion where the residual potential decreases proportionally with an increase in contact angle in the correlation curve, while the second approximate linear line denotes an approximate linear line of the portion where a change in residual potential with an increase in contact angle nearly disappears.
