    摘要： In an electrophotographic plate comprising a substrate and a photoconductive layer formed on said substrate, when said substrate is made of an age-hardening type aluminum alloy and has a Vickers hardness of 60 Hv or higher, there can be produced electrophotographic plates high in dimensional accuracy, good in resistance to mechanical damages and impact, and very small in eccentricity when molded in the form of a drum. When the surface hardness of the selenium photoconductive layer is made 5 H or harder in pencil hardness, the resulting electrophotographic plate is excellent in printing performance and has a long life.
