Abstract:
To provide a process for producing an electrophotographic photosensitive member that can not easily cause any fog due to an increase in dark attenuation, a conductive layer is formed with use of a coating liquid for conductive layer prepared with use of a solvent, a binder material and metal oxide particles. The metal oxide particles (P) and binder material (B) in the coating liquid for conductive layer are in a mass ratio (P/B) of from 1.5/1.0 to 3.5/1.0. The metal oxide particle is a titanium oxide particle coated with tin oxide doped with phosphorus or tungsten. Where powder resistivity of the metal oxide particle is represented by x (Ω·cm) and powder resistivity of the titanium oxide particle as a core particle constituting the metal oxide particle is represented by y (Ω·cm), the y and the x satisfy the following relations (i) and (ii): 5.0×107≦y≦5.0×109 (i) 1.0×102≦y/x≦1.0×106 (ii).
