摘要:
A process for producing a light-receiving member comprising a substrate and a non-monocrystalline light-receiving layer provided on the substrate, which comprises forming at least a part of the light-receiving layer by decomposing a starting material gas introducing into a reaction chamber by means of an electromagnetic wave with a frequency of from 20 MHz to 450 MHz.

A method of treating a substrate for an electrophotographic photosensitive member by a process comprises the steps of;
a) cutting the surface of the substrate to remove the surface in the desired thickness; and b) bringing the cut surface of the substrate into contact with water having a temperature of from 5°C to 90°C, having a resistivity of not less than 11 MΩ·cm at 25°C, containing fine particles with a particle diameter of not smaller than 0.2 µm in a quantity of not more than 10,000 particles per milliliter, containing microorganisms in a total viable cell count of not more than 100 per milliliter and containing an organic matter in a quantity of not more than 10 mg per liter, for at least 10 seconds at a pressure of from 1 kg·f/cm² to 300 kg·f/cm².

A light receiving member comprising a substrate and a light receiving layer disposed on said substrate, said light receiving layer having a stacked structure comprising a plurality of constituent layers each being composed of a non-single crystal material containing silicon atoms as a matrix and at least either hydrogen atoms or halogen atoms, characterized in that said light receiving layer has a region containing at least one kind of atoms selected from the group consisting of hydrogen atoms and halogen atoms at an enhanced concentration distribution in the thickness direction in the vicinity of at least one layer interface of the light receiving layer.
摘要:
In an electrophotographic apparatus having a structure for scrape-cleaning a developer of an average particle diameter of 5 to 8 µm 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 2 , 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.
摘要:
As the surface layers of an electrophotographic photosensitive member, a first surface layer which satisfies a condition that a center line average surface roughness (Ra) ranges from 50 Å to 5000 Å and a second surface layer comprising a non-single-crystal carbon containing at least fluorine are laminated in this order. Thus, the generation of a defective image such as the dimness of an image or an image smearing can be suppressed under an environment of high temperature and high humidity without providing any heater even when an electrophotographic apparatus is repeatedly employed. Further, even when a toner of small particle size and excellent in its fixing characteristic is used, a cleaning characteristic can be improved and the fusion of the toner can be suppressed. Still further, even in an electrophotographic process with a frictional force raised for improving the cleaning characteristic, the cleaning characteristic can be improved and the fusion of the toner can be suppressed.
