  Starting from effective Lagrangians which combine a gauge formulation of
Vector Meson Dominance with Chiral Lagrangians, the coupling of the phi to the
nucleon, which is zero at tree level due to the OZI rule, is calculated
perturbatively considering loop contributions to the electric and magnetic form
factors. We obtain reasonably smaller values for both form factors than those
for rho NN and consistent with the expected order of magnitude of the OZI rule
violation.
