Abstract
A unit for an image forming apparatus includes an electrophotographic photoreceptor that includes a conductive substrate, a photosensitive layer provided on the conductive substrate, and a surface layer provided so as to contact with an outermost surface of the photosensitive layer, and an exposure section that exposes the electrophotographic photoreceptor with a light having a wavelength (λ) (nm) so as to form an electrostatic latent image on a charged surface of the electrophotographic photoreceptor, wherein a surface roughness (Rz1) (nm) of the outermost surface of the photosensitive layer satisfies an expression of [(Rz1)≧(λ)/(4×(n2))] where a refractive index of the surface layer is set as (n2), and an outermost surface of the surface layer has a surface shape different from the outermost surface of the photosensitive layer.
