PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor and an electrophotographic apparatus in which effects of a corona discharge product produced by corona discharge are small, and a high-quality image without image blur or image flowing can be obtained from the first copy sheet immediately after the power supply is turned on, without need to heat the electrophotographic photoreceptor when the power supply to the electrophotographic apparatus body is in an off state, in any environment. SOLUTION: The electrophotographic photoreceptor has a photoconductive layer and a surface protective layer made of a non-single crystal material essentially comprising silicon atoms and containing at least hydrogen atoms, on a conductive substrate. When the content of hydrogen atoms included in the surface protective layer is measured by an ERDA (elastic recoil detection analysis), the hydrogen amount after the surface protective layer is irradiated with 50μC helium ions at 2.3 MeV acceleration energy is 30 to 80% of the hydrogen amount present before the irradiation with helium ions.
