A linear mapping T from a subspace E of a Banach algebra into another Banach algebra is called spectrally bounded if there is a constant M > 0 such that r(Tx) < Mr(x) for all x ∈ E, where r(.) denotes the spectral radius. We prove that every spectrally bounded unital operator from a unital purely infinite simple C*-algebra onto a unital semisimple Banach algebra is a Jordan epimorphism.
