In this paper, we introduce and study some basic properties of new classes of sets called ψ-I-closed sets and weakly ψ-I-closed sets. Moreover, we offer a new type of contra-continuous function in the context of ideal topology called contra-ψ-I continuous function and present its fundamental properties.
