  We investigate parton distributions in the virtual photon target, both
polarized and unpolarized, up to the next-leading order (NLO) in QCD. Parton
distributions can be predicted completely up to NLO, but they are
factorization-scheme-dependent. We analyze parton distributions in several
factorization schemes and discuss their scheme dependence. Particular
attentions are paid to the axial anomaly effect on the first moments of the
polarized quark parton distributions, and also to the large-$x$ behaviors of
polarized and unpolarized parton distributions.
