A charge transporting varnish comprising a phenylamino-N, N′-diphenylquinonediimine derivative represented by the formula (1) as a charge transporting substance. Thereby, while showing high solubility with respect to various organic solvents, since it shows non-aggregation property, the charge transportable varnish containing the oxidation type oligo aniline with favorable filterability can be provided. (In the formula, R 1 represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, and R 2 to R 19 are each independently a hydrogen atom, a hydroxyl group, an amino group, a silanol group, a thiol group, Carboxyl group, phosphate group, phosphate ester group, ester group, thioester group, amide group, nitro group, substituted or unsubstituted monovalent hydrocarbon group, organooxy group, organoamino group, organosilyl group, organothio group, (Acyl group, sulfone group, halogen atom is shown.) |
