Abstract
In this paper, new definitions for intuitionistic fuzzy normed spaces of f and ψ contraction map classes in classical analysis will be given. In addition, it will be shown under which conditions these transformations provide the approximate fixed point property in intuitionistic fuzzy normed spaces. The results obtained will be supported with examples.
