PURPOSE:To improve durability by relieving the thermal strains generated by a difference in the coefft. of linear expansion between a protective layer and photoconductive layer by an intermediate layer consisting of a high-polymer resin. CONSTITUTION:The photosensitive body is constituted of a conductive base 1, the photoconductive layer 2, the intermediate layer 3 and the protective layer 4. Namely, the intermediate layer 3 consisting of the soft high-polymer resin is provided between the protective layer 4 made of ceramics and the photoconductive layer 2. The thermal strains generated by a difference in the coefft. of linear expansion between the hard protective layer 4 and the photoconductive layer 3 are, therefore, relieved by the soft intermediate layer 3 interposed therebetween, by which the degradation in the adhesiveness of the protective layer 4 is prevented. Cracking of the protective layer 4 and exfoliation of the protective layer 4 are thereby prevented and the durability is improved. |
