Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization. Consequently, the T‐dual transformation laws of the full T‐dualization are obtained. At the end, the full T‐dualization is realized in double space and it is showed that Buscher procedure and double space approach are equivalent in this specific case.
