Rings that do not necessarily have a unit element will be called non-unital. We denote by Id( R ) , U( R ) , J( R ) and M n ( R ) the set of idempotents, the set of units, the Jacobson radical and the ring of n n matrices over R , r ecpectivily. An element of a ring is called clean if it is a sum of an idempotent and a unit, and a ring R is clean if its every element of R is clean. This notion was introduced by Nicholson in [Lifting idempotents and exchange rings, Trans. Amer. Math. Soc. 229 (1977) 269–278] where it was proved that every clean ring is an exchenge ring and if idempotents in the ring are central then the converse also holds. (A ring R is an exchange ring if for every there exists an idempotent such that ). Other examples of clean rings include semiperfect rings and unit-regular rings. A ring R is said to be weakly clean if for every there exist an idempotent and a unit such that We will give an example of nonclean weakly clean ring and example of a clean ring S and an idempotent such that eSe is not clean. It is shown that every clean ring is weakly clean and every weakly clean ring is exchenge. Also it is shown that weakly clean rings are closed under homomorphic images, direct limits and (arbitrary) direct products. A ring R is weakly clean if and only if R= J( R ) is weakly clean and idempotents lift modulo J( R ).
