We study the Q2 dependence of the chiral-odd twist-3 distribution e(x,Q2). The anomalous dimension matrix for the corresponding twist-3 operators is calculated in the one-loop level. This study completes the calculation of the anomalous dimension matrices for all the twist-3 distributions together with the known results for the other twist-3 distributions g2(x,Q2) and hL(x,Q2). We also have confirmed that in the large Nc limit the Q2 evolution of e(x,Q2) is wholly governed by the lowest eigenvalue of the anomalous dimension matrix which takes a very simple analytic form as in the case of g2 and hL.
