The longitudinal response function for quasielastic electron scattering is calculated in the σωρ model of quantum hadrodynamics. We use meson fields and nucleon wave functions, as obtained in mean-field theory of closed-shell nuclei, in relativistic random-phase approximation. The results for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ and ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ are compared with those of a previous calculation, where the response function was evaluated in local-density approximation. We find a shift in the position of the maximum which is due to the inclusion of binding energy effects, and a slight broadening of the response function. Comparing with the data, we find good agreement except for ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ at the highest momentum transfer q=550 MeV.
