We study the one loop contribution of the down type quark of the SM-like fourth generation (b #8242;) on the top quark electric dipole moment. Using the known limits on the top quark electric dipole moments (EDM), we place limits on the b #8242; mass. Then from the estimated ratio for the masses of the fourth generation of quarks from other studies and the achieved bound from top quark EDM on mb #8242; , we obtain a limit for the up type quark of fourth generation (t #8242;) mass.
