Abstract
A photoconductor for electrophotography including a conductive substrate, an undercoat layer provided on the conductive substrate, and a photosensitive layer provided on the undercoat layer and a manufacturing method thereof. The undercoat layer contains metallic oxide fine particles and is formed by applying a coating liquid for the undercoat layer onto the conductive substrate. The coating liquid contains an organic solvent having a boiling point at 1×105Pa of about 160° C. or less and a viscosity at 20° C. of about 3.0 mPa.s or more. This improves dispersion stability of metal oxide fine particles in the coating liquid to realize a uniform undercoat layer and, in turn, provides the photoconductor with uniform electrophotographic characteristics, in particular, with uniform image characteristics and external appearance characteristics.
