Electrophotographic photoreceptors have various configurations in order to obtain predetermined characteristics or depending on the type of electrophotographic process to which they are applied. As representative electrophotographic photoreceptors, there are photoreceptors having a photoconductive layer formed on a support and photoreceptors having an insulating layer on the surface, which are widely used. The photoreceptor, consisting of a support and a photoconductive layer, is used for image formation by the most common electrophotographic processes, ie, charging, image exposure and development, and optionally transfer. Additionally, for photoreceptors with an insulating layer, this insulating layer may be used to protect the photoconductive layer, improve the mechanical strength of the photoreceptor, improve dark decay properties, or be applied to certain electrophotographic processes ( Furthermore, it is provided for the purpose of eliminating pollution. A typical example of a photoreceptor having such an insulating layer or an electrophotographic process using a photoreceptor having an insulating layer is, for example, U.S. Pat.

される。 For example, in the case of glass, its surface is conductively treated with In 2 O 3 or SnO 2 , or in the case of a synthetic resin film such as polyimide film, it is treated with Al, Ag,
Pd, Zn, Ni, Au, Cr, Mo, Ir, Nb, Ta, V,
The surface is treated with a metal such as Ti or Pt by vacuum evaporation, electron beam evaporation, sputtering, etc., or laminated with the metal, so that the surface thereof is conductive. The shape of the support body is cylindrical, belt-shaped,
It can be of any shape, such as a plate shape, and the shape is determined as desired, but in the case of continuous high-speed copying,
It is desirable to have an endless belt shape or a cylindrical shape. The thickness of the support is determined as appropriate, but if flexibility is required, it is made as thin as possible within a range that allows the support to function satisfactorily. However, in such a case, the thickness is usually set to 10μ or more in view of manufacturing and handling of the support, mechanical strength, etc.
第一の光導電層の暗抵抗は通常1013〜1016Ω・

である。また、第一の無機光導電層の厚さは、5
μ〜70μ、特には15μ〜60μに設定するのが好適
である。 The dark resistance of the first photoconductive layer is usually 10 13 to 10 16 Ω・
cm, particularly preferably set to 10 14 to 10 16 Ω·cm. Moreover, the thickness of the first inorganic photoconductive layer is 5
It is preferable to set it to 15μ to 60μ, particularly 15μ to 60μ.

ことも有効である。 The A-Si layer is usually formed on a support by a deposition method such as a glow discharge method, a sputtering method, an ion plating method, or a vacuum evaporation method. The glow discharge method, sputtering method, and ion plating method are deposition methods that utilize a discharge phenomenon, and are methods in which a glass plasma atmosphere is maintained in a deposition chamber for a predetermined period of time to form an A-Si layer of the required thickness. Particularly effective. As the material for forming the A-Si layer, in addition to silicon itself, silicon compounds that decompose to produce silicon during deposition are used. Typical examples of such silicon compounds are:
Silicon hydrogen compounds such as SiH 4 and Si 2 H 6 .
Regarding the formation of the A-Si layer, it is also effective to add hydrogen (H), oxygen, nitrogen, and/or carbon as necessary to control the dark resistance and photoelectric gain of the A-Si layer.

で、通常シリコン単体又は他のシリコン化合物を
併用しなくてよいが、必要に応じて、これらのシ

よい。 A typical method for incorporating H into the Si layer is to introduce H into the deposition system in the form of compounds such as SiH 4 and Si 2 H 6 and/or H 2 when forming the layer, and to introduce H into the deposition system in the form of a gas discharge. Therefore, those compounds or H 2 can be decomposed to form A-Si
The layers are included in the layer as they grow. When using a silicon hydride compound such as SiH 4 or Si 2 H 6 as a material for forming the A-Si layer, silicon in this compound can be used as the main component for forming the A-Si layer, so silicon alone or other materials are usually used. Although it is not necessary to use a silicon compound in combination, these silicons alone or other silicon compounds may be used in combination, if necessary.
A−Si層中に含有されるHの量は通常の場合10
〜40atomic(原子)%、好適には15〜30atomic
