Base on the formalism in Stochastic gravity, we study the nonlinear quantum effect of the scalar field during inflation. We have shown as long as the slow-roll condition is satisfied, Einstein-Langevin equation, which describes the quantum correction of the scalar field to the gravitational field, can be solved iteratively. In these quantum corrections, there exist two different order parts; the leading part induces the equivalent effect to the linear analysis and the other part induces the nonlinear effect.
