Abstract
To provide an amorphous Si photosensitive member and an image forming apparatus which form favorable images by preventing toner adhesion at a cleaning time. A photoconductive layer containing amorphous Si is formed on an electrically conductive substrate so that a surface of a photosensitive member has an average inclination &Dgr;a within a range of 0.12 to 1.0, more preferably 0.15 to 0.8 within a range of 10 &mgr;m×10 &mgr;m, and an electrically conductive substrate has surface roughness Ra within the range of 10 &mgr;m×10 &mgr;m is lower than 9 nm, preferably lower than 6 nm.
