We have considered the effect of changing the electronic bandfilling on the basic properties of the Peierls conductor when it is neither almost empty nor close to half filled. We calculate the zero-temperature gap |Δ|o as well as the relation between |Δ|o and the transition temperature Tc in the mean field approximation. When necessary we maintain cthe specific wavevector dependence of the electron-phonon coupling appropriate for the tight binding approximation. Our results are relevant for the interpretation of charge transfer salts with intermediate bandfillings.
