PURPOSE:To obtain an electrophotographic sensitive body superior in resistances to scratching and ozone oxidation, high in sensitivity and durability, and suitable for positive electrification by incorporating an electric charge transfer material in a charge generating layer, and a specified compound in this layer or a protective layer. CONSTITUTION:The electrophotographic sensitive body is obtained by successively laminating the charge transfer layer, the charge generating layer, and when needed, the protective layer on a conductive substrate, and it contains the charge transfer material in the charge generating layer and in this layer or the protective layer the compound represented by the formula shown on the right in which R is H, alkyl, aryl, or aralkyl and R' is alkyl. When this compound is added to the charge generating layer, it is contained in an amount of 0.1-100wt%, preferably, 1-50wt%, especially, 5-25wt% of the charge transfer material contained in the charge generating layer, and when it is added to the protective layer, it is contained in an amount of 0.1-100wt%, preferably, 1-50wt% of the binder resin of this layer. |
