<p>The present invention provides an electrophotographic photosensitive member including a photoconductive layer, an intermediate layer made of hydrogenated amorphous silicon carbide on the photoconductive layer, and a surface layer made of hydrogenated amorphous silicon carbide on the intermediate layer, wherein a ratio (C/(Si+C); C2) in the surface layer is 0.61 to 0.75, and a sum of atom density of silicon and carbon is 6.60 × 10 22 atoms/cm 3 or more, a ratio (C/(Si+C); C1) and a sum (D1) of atom density of silicon and carbon in the intermediate layer increase continuously from the photoconductive layer toward the surface layer without exceeding C2 and D2, and the intermediate layer has a continuous region in which C1 is 0.25 to C2 while D1 is 5.50 × 10 22 to 6.45 × 10 22 atoms/cm 3 , the region being 150 nm or larger in a layer thickness direction, and an electrophotographic apparatus equipped therewith.</p> |
