Let ϕ(n) denote the Euler totient function. We study the error term of the general kth Riesz mean of the arithmetical function n/ϕ(n) for any positive integer k ≥ 1, namely the error term where . For instance, the upper bound for |Ek(x)| established here improves the earlier known upper bounds for all integers k satisfying .
