Abstract
An image-forming method uses an electrophotographic photosensitive member having a surface layer formed of a hydrogenated amorphous silicon carbide in which a ratio of the number of carbon atoms to the sum of the number of silicon atoms and the number of the carbon atoms in the surface layer is 0.61 or more and 0.75 or less, and the sum of the atomic density of the silicon atoms and the atomic density of the carbon atoms in the surface layer is 6.60×10atoms/cmor more, and the peak wavelength of pre-exposure light is shorter than the peak wavelength of image exposure light.
