Abstract

PURPOSE:To maintain high sensitivity at the time of repeated uses and to prevent deterioration of chargeability characteristics and image density and background staining by incorporating aliphatic alcohol in an interlayer in an electrophotographic sensitive body obtained by successively laminating the interlayer and a photosensitive layer on a conductive substrate. CONSTITUTION:The electrophotographic sensitive body is formed by successively laminating the interlayer 2 containing the aliphatic alcohol, not only monohydric alcohols but also polyhydric alcohols, and the photosensitive layer 3 on the conductive substrate 1. This interlayer 2 is formed in order to prevent injection of charge carriers from the conductive substrate 1 to the photosensitive layer 3 at the time of charging of the photosensitive body on purpose to maintain chargeability, and transfers carriers generated in the photosensitive layer 3 at the time of exposure to the side of the conductive substrate 1, and these carriers are reverse in polarity to those prevented from injection to the conductive substrate 1, thus permitting chargeability characteristics not to be deteriorated at the time of repeated uses and a sharp copied image free from deterioration of image density and background staining to be obtained.
