Zusammenfassung:PURPOSE:To obtain an electrophotographic sensitive body which is highly sensitive with long wavelength light of >=800nm and is excellent in physical characteristic in a function sepn. type photosensitive body by using a specific phthalocyanine compd. in forming an electric charge generating layer. CONSTITUTION:The phthalocyanine compd. (InIPc, C32H16N8IIn) expressed by the formula (Me is indium; X is iodine) is used. More specifically, the InIPc is deposited by a vapor deposition method with resistance heating on a conductive substrate (e.g.; aluminum plate) 61 to form an electric charge generating layer 62 to about 0.2mu thickness and after said layer is exposed for about 20hr in THF vapor, the THF soln. of a polyvinyl carbazole resin for electrophotography is coated thereon and the solvent (THF) is evaporated to form an electric charge transport layer 63 having about 8mu thickness, by which the electrophotographic sensitive body is obtd.
