An aniline derivative represented by formula (1) is provided.[In formula (1), R<sup>1</sup> to R<sup>5</sup> are each independently a hydrogen atom or a group represented by formula (2) or (3)(wherein Ar<sup>1</sup> and Ar<sup>2</sup> each independently represent a C<sub>6-20</sub> aryl group and Ar<sup>3</sup> represents a C<sub>6-20</sub> arylene group, any two of Ar<sup>1</sup> to Ar<sup>3</sup> may be bonded to each other to form a ring in cooperation with the nitrogen atom, R<sup>6</sup> to R<sup>8</sup> each independently represent a C<sub>1-20</sub> alkyl or C<sub>6-20</sub> aryl group optionally substituted by W<sup>1</sup>, and W<sup>1</sup> represents a halogen atom, a nitro group, a C<sub>1-20</sub> alkoxy group, or a cyano group), at least one of R<sup>1</sup> to R<sup>5</sup> being a group represented by formula (3).] |
