The Charney-Hasegawa-Mima equation, with random forcing at the narrow band wave-number region, which is set to be slightly larger than the characteristic wave number λ, evaluating the inverse ion Larmor radius in plasma, is numerically studied. It is shown that the Fourier spectrum of the potential vorticity fluctuation in the development of turbulence with an initial condition of quiescent state obeys a dynamic scaling law for k≪λ. The dimensional analysis with the assumption that the energy transfer rate ε in the inverse cascade is constant with time leads to the scaling form S(k,t) = λ1/2ε5/4t 7/4F(k/k(t))[k(t)~λ3/4ε -1/8t-3/8] with a scaling function F(x), which turns out to be in good agreement with numerical experiments
