    摘要: An electrophotosensitive material comprising a supporting substrate, an intermediate layer containing a thermosetting resin formed on the supporting substrate, and a photosensitive layer formed on the intermediate layer, wherein a contact angle of the surface of the intermediate layer is not less than a value (Anull) represented by the formula: AnullnullBnullnull2null in which Bnull is a contact angle corresponding to an intersection of a first approximation linear line and a second approximate linear line minus 2null in a correlation curve between a residual potential of the photosensitive material comprising the predetermined photosensitive layer formed on the intermediate layer containing the thermosetting resin and a contact angle of the intermediate layer containing the thermosetting resin. According to this photosensitive material, it is possible to obtain a good image, which has a low residual potential and is free from fog.

    摘要: The invention relates to an electrophotosensitive material comprising an intermediate layer formed between a conductive substrate and a photosensitive layer, and featuring heat treatment conditions for forming the intermediate layer defined such that a ratio A2/A1 between absorbances at two measurement wavelengths determined from a visible absorption spectrum of the intermediate layer is not more than a value of an intersection of a first approximation line and a second approximation line given by a correlation distribution between the absorbance ratio and the residual potential of the photosensitive material, the first approximation line representing little change of the residual potential despite the increase of the ratio A2/A1, the second approximation line representing a proportional increase of the residual potential with increase of the ratio A2/A1. The invention provides the electrophotosensitive material free from the variations of residual potential.
