An electrophotographic photoreceptor includes a conductive substrate, an organic photosensitive layer that is provided on the conductive substrate, and an inorganic protective layer that is provided on the organic photosensitive layer, wherein the inorganic protective layer includes a first layer, a second layer, and a third layer in this order from the organic photosensitive layer side and satisfies the relationship of the following expression (1):n nρ3≦ρ1<ρ2 Expression (1):n nwherein ρ 1 represents a volume resistivity (Ω·cm) of the first layer, ρ 2 represents a volume resistivity (Ω·cm) of the second layer, and ρ 3 represents a volume resistivity (Ω·cm) of the third layer. |
