摘要： In an electrophotographic plate, that having an undercoating layer with smooth surface when observed by using a scanning electron microscope and an electric conductivity of at least 2.times.10.sup.-14 .OMEGA..sup.-1 .multidot.cm.sup.-1 between an electroconductive substrate and a photosensitive layer is improved in electrophotographic properties which are hardly changed by changes of circumstances.
