A bounded linear operator A on a Banach space is called relatively regular, if there is a bounded linear operator B such that ABA = A. In this case B is called a g 1 -inverse of A. In this paper we characterize some classes of relatively regular operators A via the set {B 1 -B 2 : B 1 and B 2 are g
