We show that the resummation of large radiative corrections in QCD processes can be performed both in the covariant gauge and in the axial gauge. We extend the resummation technique to inclusive processes, concentrating on deep inelastic scattering, Drell-Yan production, and inclusive heavy meson decays in end-point regions. Leading and next-to-leading logarithms produced by radiative corrections are organized into Sudakov factors, whose expressions are the same as those derived from the conventional Wilson-loop approach. The gauge invariance of the resummation in the end-point region is demonstrated explicitly. {copyright} {ital 1997} {ital The American Physical Society}
