  In this paper, we present new results on holomorphically accretive mappings
and their resolvents defined on the open unit ball of a complex Banach space.
  We employ a unified approach to examine various properties of non-linear
resolvents by applying a distortion theorem we have established. This method
enables us to prove a covering result and to establish the accretivity of
resolvents along with estimates of the squeezing ratio. Furthermore, we prove
that under certain mild conditions, a non-linear resolvent is a starlike
mapping of a specified order.
  As a key tool, we first introduce a refined version of the inverse function
theorem for mappings satisfying so-called one-sided estimates.
