Abstract
We calculate the skewed quark distributions (SQDs) of the pion in the light -front quark model, and discuss the calculation of the nonvalence contribut ion to the SQDs in this model. The frame independence of our model calculat ion is guaranteed by the constraint of the sum rule between the SQDs and fo rm factor. Our numerical results show large nonvalence contributions to the SQDs at a small momentum transfer region as the skewedness increases.
