けたことに基づく。Conventionally, it has been known that polymers of pyrrole and virol derivatives can be formed into thin films by electrolytic polymerization or chemical polymerization from the gas phase, and that conductivity can be increased by introducing anions. However, no attempt has been made to use this thin film as a charge generation layer of a multilayer 1-type electrophotographic photoreceptor. The present invention is based on the discovery that applying the above-mentioned anion-doped thin film to the charge transport layer of a photoreceptor is superior both in terms of characteristics and economy.

より速やかに電荷輸送層へ注入される特徴を持つ。In the present invention, as shown in FIG. 1, a polypyrrole or polypyrrole derivative film is formed on a conductive support by an electrolytic polymerization method or a gas phase polymerization method, and an anion is further doped to form a charge generation layer 2. Thereafter, a charge transport layer is formed thereon to produce an electrophotographic photoreceptor. Since polypyrrole has a broad absorption band throughout the visible light region, it is thought that it generates carriers in visible light. Furthermore, since it has high conductivity, generated carriers are quickly injected into the charge transport layer by an external electric field.

After the polypyrrole film is depolymerized, the solvent is sufficiently removed, and then a material transport layer is formed. As the charge transport layer, a known organic compound such as PvK (polyvinylcarbazole) may be used. The present invention will be described in detail below with reference to Examples. In the examples below, only the depolymerization method will be described as the method for forming polypyrrole, but the method for forming a thin film is not limited to electrolytic polymerization, and chemical polymerization from a gas phase can also be used. It is clear that there is.

The film thickness was proportional to the polymerization time and was 0.5 μm or less. Further, when the film polymerized for 5 minutes was examined for variation in film thickness, only a variation of about ±10% or less was observed within one film. The electrical conductivity of this film was 23.75 m as measured by the four-probe method. Furthermore, a monochlorobenzene solution containing 8% P''vK (polyvinylcarbazole) was coated on top of this film using a spinner to a thickness of 8 μm to form a charge transport layer. The electrophotographic characteristics were investigated under the conditions of charging knee 6 kV dark discharge: 5 seconds exposure intensity 20 mW/ctl (white light).The acceptance potential V when this sample was corona charged, the decay rate immediately before exposure was Vd, and the start of exposure was The attenuation speed at the time of the test was taken as Vl, and the values shown in Table 1 were obtained.
