We present the results of the gluino and scalar quark contribution to the flavor-changing top quark decay into a charm quark and a photon, gluon, or a {ital Z}{sup 0} boson within the minimal supersymmetric standard model. We include the mixing of the scalar partners of the left- and right-handed top quark. This mixing has several effects, the most important of which is to greatly enhance the {ital c} {ital Z} decay mode for large values of the soft SUSY-breaking scalar mass {ital m}{sub {ital S}} and to give rise to a GIM-like suppressions in the {ital c} {gamma} mode for certain combinations of parameters.
