Abstract
We investigate the renormalization of the twist-3 operators which are relevant for the spin-dependent structure function g2(x, Q2). We derive the anomalous dimension for the non-singlet part by calculating the off-shell Green's functions of the twist-3 operators including the operators which are proportional to the equation of motion.
