#### Abstract

We prove that a real hypersurface M in a complex space form Mn(c), $c{\neq}0$, whose Ricci operator and structure tensor commute each other on the holomorphic distribution and the Ricci operator is ${\eta}-parallel$, is a Hopf hypersurface. We also give a characterization of this hypersurface.

#### Keywords

real hypersurfaces in complex space forms;Hopf hypersurfaces;model spaces of type A or B
