  The Wilson contour integral approach is applied to resum the soft gluon
radiative correctins to the quark form factors in the Sudakov regime. The
one-loop order results for the quark-photon (color singlet form factor) and
quark-gluon (color non-singlet form factor) vertices are presented. The
explicit expressions for the vacuum averaged contour integrals in $g^2$
accuracy are derived for an arbitrary gauge field. The corresponding one-loop
cusp anomalous dimensions are found in the case of perturbative gluon field in
arbitrary covariant gauge. It is shown that the gauge dependence drops out from
the leading high energy behavior.
