Abstract:
1. An electrophotographic apparatus which comprises an electrophotographic photosensitive member having a surface layer with an amorphous silicon carbide, wherein; a ratio of an atom density (C) of carbon atoms to a sum of an atom density (Si) of silicon atoms and the atom density (C) of carbon atoms, C/(Si+C), in the surface layer is set larger from one end portion toward the other end portion of the electrophotographic photosensitive member in the direction of a rotational axis thereof, and is from 0.61 or more to 0.75 or less in the entire region of the electrophotographic photosensitive member in the direction of the rotational axis thereof; the sum of the atom density of silicon atoms and the atom density of carbon atoms in the surface layer is 6.60×10 the electrophotographic apparatus has an air current generation means which draws out air from a side of the one end portion toward a side of the other end portion.
