PURPOSE:To obtain the titled body which has excellent electric chargeability, high photosensitivity, excellent printing resistance, and less residual potential and is capable of forming excellent copying image by composing an electric charge transfer substance of a specific carbazole derivative. CONSTITUTION:The titled body is provided with a layer of the electric charge transfer substance and a layer of the electric charge generating substance on a conductive substrate body. The electric charge transfer substance is composed of the carbazole derivative shown by the formula wherein R<1> and R<2> are each 1-4C alkyl group. The electric charge transfer substance contd. in the electric charge transfer layer is exemplified by 3,6-bis(dialkyl amino)-9-alkyl carbazole, and the compounding amount of said compd. is preferably a range of 10-60wt% per the weight basis of said layer. The thickness of the electric charge transfer layer is suitable to be 5-100mum. The less the sticking resin is used in the electric generating layer, the more the titled body is preferable, and the content of the sticking resin is preferably 5-50wt%. The thickness of the electric charge generating layer is usually 0.05-20mum, preferably 0.1-10mum. |
