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.
