We report results on semileptonic Image decay form factors near qmax2 using NRQCD heavy quark and clover light quark actions and currents improved through O(αa). An inconsistency with the soft pion relation f0 (qmax2 = fB / fπ found in a previous work is confirmed, and a possible solution with nonperturbative renormalization is discussed. We find that f+(q2) is well described by the B* pole near qmax2, and its 1/MB scaling is also consistent with the prediction of the pole dominance model.
