Abstract:
A production method for an electrophotosensitive material comprising a conductive substrate, an intermediate layer containing a thermosetting resin, and a photosensitive layer, the intermediate layer being laminated on the conductive substrate and the photosensitive layer being laminated on the intermediate layer, comprising the steps of:previously deriving a correlation distribution between a ratio A2/A1 of absorbance A1 measured at a first measurement wavelength W1 which is a predetermined wavelength on a shorter-wave side of a maximum absorption wavelength in a visible absorption spectrum of the intermediate layer to absorbance A2 measured at a second measurement wavelength W2 which is a predetermined wavelength on a longer-wave side of the maximum adsorption wavelength and a residual potential of the photosensitive material from a plurality of heat treatment conditions for curing the thermosetting resin during the formation of the intermediate layer; forming the intermediate layer containing the thermosetting resin on the conductive substrate; and overlaying the photosensitive layer selectively on the formed intermediate layer when the ratio A2/A1 determined from a visible absorption spectrum of the intermediate layer is not more than the value corresponding to an intersection of a first approximation line representative of a portion where an increase of the ratio A2/A1 involves relatively little change in the residual potential and a second approximation line representative of a portion where the increase of the ratio A2/A1 involves a proportional increase of the residual potential in the correlation distribution.
