We estimate the isospin-violating QED radiative corrections to the charged-to-neutral ratios of the decay rates for B+ and B0 in non-leptonic B meson decays. In particular, these corrections are potentially important for precision measurement of the charged-to-neutral production ratio of B meson in e+e- annihilation. We calculate explicitly the QED corrections to the ratios of two different types of decay rates Γ(B+→J/ψK+)/Γ(B0→J/ψK0) and [Formula: see text] taking into account the form factors of the mesons based on the vector meson dominance model, and compare them with the results obtained for the point-like mesons.
