Abstract
A positively charged organic photosensitive body is provided, the photosensitive body being free from public hazards, and being highly sensitive and highly durable. The photosensitive body has a photosensitive layer of a laminated structure on a conductive substrate. The photosensitive layer has a charge transport layer (I) having hole mobility, a charge generation layer, and a charge transport layer (II) containing a curing product of a doped amino resin and having electron mobility. The charge transport layer (I), the charge generation layer, and the charge transport layer (II) are laminated in this order on the conductive substrate. Various suitable substances may be added to the charge transport layer (II), thereby enhancing its durability without deteriorating the photosensitive characteristics.
