Abstract
In an electrophotographic apparatus having a structure for scrape-cleaning a developer of an average particle diameter of 5 to 8 &mgr;m with an elastic rubber blade having a modulus of repulsion elasticity of not less than 10% nor more than 50%, by using a light receiving member having a surface layer comprised of a non-monocrystalline fluorinated carbon film in which the wear loss after copying steps of 10,000 A4-size transfer sheets is not less than 0.1 Å nor more than 100 Å, in which the dynamic hardness is within the range of 10 to 500 kgf/mm,, and in which the fluorine content is not less than 5 atomic % nor more than 50 atomic %, an electrophotographic apparatus is provided which can prevent scattering or fusion of a developer, uneven scraping of a surface layer and image smearing irrespective of the service environment conditions and also can prevent image smearing without provision of means for directly heating the light receiving member.
