ABSTRACT:
An object of the invention is to provide an electrophotographic photoconductor featuring uniform chargeability to a predetermined potential, low residual potential and excellent stability in the operating environment and repeated use thereof, as well as a method of producing the same. An undercoat layer between a substrate and a photosensitive layer is formed by the use of a coating fluid for undercoat layer containing a coupling agent having an unsaturated bond, a metal oxide, a binder and a mixture solvent. The coupling agent increases affinity of the metal oxide for the binder so that the coating fluid does not suffer the aggregation of the metal oxide or gelation thereof, presenting homogeneity and excellent can-stability. Thus is obtained a uniform undercoat layer. A photoconductor having this undercoat layer is adapted to be uniformly charged to a predetermined potential and to suppress the rise of residual potential and particularly the rise of residual potential due to a use thereof under low-temperature, low-humidity conditions or the repeated use thereof over an extended period of time, thus offering a high photosensitivity in a stable manner.
