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.
