    The authors show that in a ring of stable range 1, any (von Neumann) regular element is clean. The main results of this paper also imply that any unit-regular ring has idempotent stable range 1 (and is therefore clean), and that a semilocal ring has idempotent stable range 1 if and only if it is semiperfect.
