We present a maximum-entropy imaging algorithm using the bispectrum observed with radio interferometers. It is iterative and based on the steepest-ascent method. Imaging simulation tests show that this algorithm can reconstruct more reliable images of weak, extended sources than can the conventional self-calibration method. An example application of this algorithm to data of the Nobeyama Millimeter Array is given.
