The relativistic nuclear mean-field model with derivative scalar coupling suggested by Zimanyi and Moszkowski is extended to finite temperature by means of the real-time Green's function method with a pair cutoff approximation. The temperature and density dependences of the nucleon masses are given. The obtained equation of state is used to discuss the liquid-gas phase transition of nuclear matter. The critical temperature and density given by this model are [ital kT][sub [ital C]]=16.51 MeV and [rho][sub [ital C]]=0.0675 fm[sup [minus]3], respectively.
