  The scaling behavior of the quantum phase transition from an insulator to a
quantum Hall plateau state has often been examined within systems realizing
Landau levels. We study the topological transition in energy band models with
nonzero Chern number, which have the same topological property as a Landau
level. We find that the topological band generally realizes the same
universality class as the integer quantum Hall system in magnetic field for
strong enough disorder scattering. Furthermore, the symmetry of the transition
characterized by the relations: $\sigma_{xy}(E)=1-\sigma_{xy}(-E)$ for the Hall
conductance and $\sigma_{xx}(E)=\sigma_{xx}(-E)$ for the longitudinal
conductance is observed near the transition region. We also establish that the
finite temperature dependence of the Hall conductance is determined by the
inelastic scattering relaxation time, while the localization exponent $\nu$
remains unchanged by such scattering.
