An electrophotosensitive material of the present invention is formed by providing a photosensitive layer containing a bis-azo pigment expressed in formula (1): ##STR1## wherein A.sup.1, A.sup.2, R.sup.1 and n are as defined, as a charge generating material, and a diamine compound expressed in formula (2): ##STR2## wherein R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 p and q k, l, m and o are as defined, as a charge-trasferring material, on a conductive substrate. As a charge generating material, a perylene pigment, anthanthrone pigment, X-type metal-free phthalocyanine pigment, imidazoleperylene pigment or perylene bis-azo pigment are preferable used together with the bis-azo pigment. Thus, photosensitive material is excellent in sensitivity and durability.
