In this paper, category IFuz of intuitionistic fuzzy sets (IFS) is built up and two objects (middle object and WSC) are introduced in IFuz. By the use of middle objects and WSC, category IFuz makes a wtopos. Wtopos has similiar functions to topos. So logic operators can be obtained logically.&lt;br /&gt;
