PURPOSE:To obtain a function separating type photosensitive body constituted of a charge generating layer and a charge transfer layer having superior charge transfer capacity,chargeability providing sufficient surface potential even in the case of thin film thickness by forming the charge transfer layer of a specified amorphous carbon film contg. H. CONSTITUTION:A function separating type photosensitive body constituted of a charge generating layer 3 and a charge transfer layer 2 is obtd. by forming the charge transfer layer 2 of amorphous C film contg. H, wherein the ratio (N1:N2) between the number (N1) of C atoms bonded to H and the number (N2) of C atoms not bonded to H in its chemical structure is regulated to 1:0.1-1:1. Said a-C film is formed as the charge transfer layer 2. The film thickness of the a-C film is pref. 5-50mum, most pref. 7-30mum. The a-C film layer has light transmittivity and high dark resistance, as well as high charge transfer capacity. The layer can transfer carrier without generating trap of charge even if the film thickness is increased to >=5mum. |
