<p>PROBLEM TO BE SOLVED: To provide an electrophotographic device which attains the compatibility of the prevention of contamination of a photoreceptor with the durability of the photoreceptor. SOLUTION: In the electrophotographic device having at least the organic photoreceptor, lubricant supplying means for supplying a lubricant to the surface of the organic photoreceptor, an elastic rubber cleaning blade touched to the organic photoreceptor and toners externally added with a metal oxide, the uppermost surface layer of the organic photoreceptor contains >=1 kind of friction lowering agent selected from the group consisting of silicone oil, Al2 O3 , TiO2 , SiO2 and metal fluoride, the maximum static friction coefficient of the photoreceptor surface is <=0.4 and the abrasion loss of the photoreceptor is 0.1 to 1.0 mm per 100,000 revolutions.</p> |
