ABSTRACT:
In an electro-photographic photosensor wherein amorphous silicon as a photoconductive layer is formed on the surface of an aluminum base which has been processed to be alumite layer consisting of a porous layer and barrier layer, amorphous silicon is formed directly on the surface of the porous layer in which porosities is remained by the elimination of the process of sealing porosities. Further, when aluminum is processed by electrolyzation to be alumite, thickness of the barrier layer and the porous layer are appropriately set to provide good adhesive strength of amorphous silicon to the aluminum base and good electrostatic characteristics by adjusting respectively a voltage and duration of the electrolyzation.
