Spin fluctuation-induced superconductivity is studied on a two-dimensional d - p model by using a strong coupling theory, and is applied to interpret high- T c cuprates. A self-consistent renormalization scheme is employed within the so-called fluctuation exchange (FLEX) approximation or the renormalized random phase approximation (RRPA). Using the band parameter values which approximately reproduce the observed Fermi surface and the d - and p -hole numbers estimated from NMR experiments, we get reasonable values for T c in an optimum and overdoped concentration range. The dynamical susceptibility, the nuclear spin-lattice relaxation rate and the one electron spectral density are well compared with the existing experimental results.
