Abstract
We study the problem when a ring which is an extension of a commutativ e idempotent ring by a commutative idempotent ring is commutative. In particular, we answer Sands' question showing that the class of commut ative idempotent rings whose every homomorphic image has zero annihila tor is a maximal but not the largest radical class consisting of commu tative idempotent rings.
