  We investigate the scale dependence of transverse momentum dependent(TMD)
gluon distribution in saturation regime. We found that in the Collins-2011
scheme, the scale dependence of small x gluon TMD is governed by the same
renormalization group(RG) equation that holds at moderate or large $x$.
Following the standard procedure, one then can resum both double leading
logarithm and single leading logarithm in saturation regime by jointly solving
the Collins-Soper equation and the RG equation.
