A link between the spin structure and the shape of the Fermi surface is systematically explored for the single-band repulsive Hubbard model with the fluctuation exchange (FLEX) approximation. The authors show that (1) the experimentally observed band filling dependence of the peak position of the spin structure in the high {Tc} cuprates can be understood for both the hole-doped (YBCO, Bi2212) and electron-doped (NCCO) regimes. (2) For La{sub 2{minus}x}Sr{sub x}CuO{sub 4}, the spin-structure incommensurability and the ARPES result for the Fermi surface can be understood simultaneously if the second nearest neighbor hopping decreases with the hole doping.
