In this article we prove that the Riesz equality holds for conjugate functions which are Denjoy integrable in the restricted sense. As a corollary one obtains that if the conjugate function is Denjoy integrable in the restricted sense, then the conjugate series coincides with the Fourier–Denjoy series of the conjugate function.
