By electrotreating a dispersion or solution obtained by dispersing or dissolving hydrophobic substance powder in aqueous medium with the use of surfactant having a HLB value of 10.0 to 20.0, under the conditions for forming the thin film of said hydrophobic substance on the cathode, thin films of hydrophobic substance is formed on the cathode. In this way thin films of hydrophobic substance can be formed on base metals such as aluminum, which can be applied to photosensitive materials and the like.
A process for producing a thin film comprising forming a charge carrier generation layer by electrotreating a dispersion or a solution obtained by dispersing or dissolving a hydrophobic substance powder, said substance being a charge carrier generation substance, said dispersion or solution containing a surfactant having a HLB value of 10.0 to 20.0 to form a thin film of said hydrophobic substance on a cathode, wherein the powder has an average particle diameter of not more than 10 m
