In this paper, we study coposinormal composition operators and posinormal weighted composition operators on the Hardy space H2 (D). We show that if Wψ,ϕ is coposinormal on H2 (D), then ψ never vanishes on D also we prove that ϕ is univalent. Moreover, we study the commutant of a coposinormal weighted composition operator.
