Abstract
The present invention relates to improvements in a substrate for producing an electrophotographic sensitive member having a photoconductive layer formed with amorphous silicon. An electrophotographic sensitive member, which is superior in moldability, corrosion resistance, strength, charging electric potential and the like, is formed when an aluminium material, which contains at least one of iron and manganese or a combination of each at 0.30 or less % by weight, is used as a substrate on which a photoconductive layer formed with amorphous silicon is laminated; and/or the surface roughness of said substrate is 0.5 S or less; and/or an aluminium substrate containing magnesium at 0.5 to 10.0% by weight is used.
