Patent ID: 6958204

Claim:
A process for producing an electrophotographic photosensitive member containing a charge generating material and a charge transfer material, comprising the steps of synthesizing a triarylamine compound from a diarylamine and an aryl halide in the presence of a catalyst comprising a phosphine compound represented by formula (1) and a palladium compound; dissolving the triarylamine compound into a solvent to prepare a coating solution for a photosensitive layer; applying the coating solution onto an electrically conductive support; and drying the coating solution: wherein Ar 1 to Ar 3 are each independently an alkyl or aryl group which may have a substituent group, and at least one of Ar 1 to Ar 3 is an aryl group which may have a substituent group, and at least one of Ar 1 to Ar 3 is a tert-butyl group.
