Within a field-theoretical model containing the nucleon [ital N] and the pion [pi] as well as the baryons and mesons [Delta], [rho], [omega], [epsilon] as the leading [pi][pi] and [pi][ital N] resonances, a nonperturbative, relativistic calculation of the form factors of the strong meson-baryon interactions is presented. We introduce a physical self-consistent regularization'' which leads to a parameter free and nonperturbative determination of the form factors within a one-loop-ladder approximation. The results support monopole parameters in the range [Lambda]=0.5--0.9 GeV for [pi], [epsilon], [rho], and [omega] [ital NN] interactions. The method allows a consistent description of the one- and two-nucleon problem.
