We present an improved quark mass density-dependent model with the nonlinear scalar sigma field and the {omega}-meson field. By comparing with the quark-meson coupling model, we show that our model can successfully describe saturation properties, the equation of state, the compressibility and the effective nuclear mass of nuclear matter under the mean field approximation.
