摘要:
An electrophotosensitive material of the present invention is formed by providing a photosensitive layer containing a bis-azo pigment expressed in formula (1):
wherein A¹, A², R¹ and n are as defined, as a charge generating material, and a diamine compound expressed in formula (2):
wherein R², R³, R⁴, R⁵, R⁶ and R⁷ 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.
