ABSTRACT:
The invention disclosed relates to a photosensitive member which comprises a conductive substrate, a first amorphous silicon: germanium layer, an amorphous silicon layer formed on said first layer and having a thickness of about 10 to 100 .mu.m and a second amorphous silicon: germanium layer formed on said amorphous silicon layer and having a thickness of less than about 4 .mu.m. The photosensitive member of the present invention has improved sensitivity toward long wavelength light and excellent chargeability, and is free of residual potential and interference phenomena.
