Abstract
An electrophotographic apparatus has an electrophotographic photosensitive member having a surface layer of an amorphous silicon carbide. The ratio of the atom density (C) of carbon atoms to the sum of the 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 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 rotational axis thereof. The electrophotographic apparatus has an air current generator which draws out air from the side of the one end portion toward the side of the other end portion.
