  Pauli form factors of electron and muon are studied in nonlocal quantum
electrodynamics. We calculate one loop QED correction to their Pauli form
factors. The relativistic regulator is generated by the correlation function in
the nonlocal interaction. The cut-off parameter $\Lambda$ in the regulator is
determined to get the consistent anomalous magnetic moments of electron and
muon at the same level as local QED. When momentum transfer is large, there
exists obvious difference between nonlocal and local QED.
