PURPOSE:To improve the heat and wear resistances of an electrophotographic sensitive body by forming a surface layer consisting of two carbon layers contg. boron on the photoconductive layer made of amorphous silicon contg. hydrogen. CONSTITUTION:A photoconductive layer 2 and a surface layer 1 are successively laminated on an electrically conductive substrate 3 to obtain an electrophotographic sensitive body. At this time,the surface layer 1 on the photoconductive layer 2 made of amorphous silicon contg. hydrogen is composed of upper and lower amorphous carbon layers contg. <=50atom% hydrogen. The amorphous carbon layers also contain boron, the concn. of boron in the upper layer is 10<-4>-1.0atom%, and that in the lower layer is 0.1-1.0atom%. Thus, the heat and wear resistances of the sensitive body are improved. |
