An electrophotographic photoreceptor using a non-contact type charging process has a creep value C.sub.I.tau. of is 2.70% or more, preferably 3.00% or more, and a Vickers hardness (HV) at its surface of 20.ltoreq.HV.ltoreq.25 in a case where a maximum indenting load of 30 mN is loaded to the surface under a circumstance at a temperature of 25.degree. C. and at a relative humidity of 50%. Since such an electrophotographic photoreceptor is excellent in flexibility and has plasticity not too soft nor exhibiting fragility, the amount of film reduction due to wear is decreased during long time use, excellent surface smoothness is ensured, and there is no occurrence of injury or unevenness in density to the formed images.
