PURPOSE:To improve the uniformity of film formation and the uniformity of electrical, optical and photoelectrical characteristics by using an aluminum alloy which consists essentially of aluminum, contains 0.5-7wt% silicon and has 50-100Hv Vickers hardness as a surface-treated metallic body to be used for the substrate of a photoconductive member. CONSTITUTION:The substrate consists of the metallic body 1 formed with the ruggedness by plural spherical trace depressions 4 on the surface. The body 1 is the aluminum alloy which consists essentially of aluminum, contains 0.5-7wt% silicon and has 50-100Hv Vickers hardness. A port hole pipe or mandrel pipe obtd. by ordinary extrusion of an aluminum alloy, etc. is further drawn and the drawn pipe obtd. in such a manner is subjected to a treatment such as heat treatment or tempering, then the substrate is formed from such cylinder in the case of using the surface-treated metallic body as the substrate of the photoconductive member such as electrophotographic sensitive body. |
