A relativistic quark potential model is employed to study the electromagnetic form factors of the proton and neutron. Moreover, the pion meson cloud effect is also taken into account. The nucleon wave function is described in an extended Fock space with the intermediate states N and Delta. The result shows the important role of the meson cloud on the neutron electroic form factor.
