Electrophotographic photosensitive member, electrophotographic apparatus and process for forming an electrophotographic image using laser and special organic photoconductor
 An electrophotographic apparatus comprises at least a charging means, an imagewise exposure means with a laser beam having a spot diameter of 100 um or less, a developing means, a transferring means and a cleaning means arranged around an electrophotographic photosensitive member, and said electrophotographic photosensitive member comprises a charge generation material and a charge transport material comprising an organic photoconductive material and has a surface layer containing said charge transport material, wherein the absorption end of visible to UV spectroscopic absorption of the surface layer is substantially unchanged by exposure to nitric acid vapor for 10 minutes; an electrophotographic image forming process; and an electrophotographic photosensitive member.
