In this paper, we introduce the concepts of w-compatible of type (I) and type (II) on d-complete topological spaces. After then we give an implicit relation and prove a fixed point theorem for w-compatible of type (I) or type (II) mappings satisfying an implicit relation on d-complete Hausdorff topological spaces.
