ABSTRACT:
An electrophotographic photoconductor having superior electrical properties and image quality which are not affected by the external environment is provided. The photoconductor includes an intermediate layer formed between a conductive substrate and a photosensitive layer. The intermediate layer is a hardened film containing as its main components melamine resin, aromatic carboxylic acid and/or aromatic carboxylic anhydride, and fixed iodine. Alternatively, the intermediate layer is composed of normal-butylated melamine resin, acid and/or an acid equivalent, and fixed iodine. The film thickness of the intermediate layer according to the present invention need not be as thin as in the prior art. An intermediate layer of such a thickness can cover various defects on the surface of the conductive substrate, and a uniform photosensitive layer with few film defects can be formed on the intermediate layer. In particular, even in the case of a photoconductor with a photosensitive layer composed of a charge-transfer layer laminated on a charge-generation layer, a thin-film, charge-generation layer can be easily formed without experiencing non-uniform film growth.
