  Let $R$ be a commutative ring with identity. In this paper, we introduce the
concept of quasi $J$-ideal which is a generalization of $J$-ideal. A proper
ideal of $R$ is called a quasi $J$-ideal if its radical is a $J$-ideal. Many
characterizations of quasi $J$-ideals in some special rings are obtained. We
characterize rings in which every proper ideal is quasi $J$-ideal. Further, as
a generalization of presimplifiable rings, we define the notion of quasi
presimplifiable rings. We call a ring $R$ a quasi presimplifiable ring if
whenever $a,b\in R$ and $a=ab$, then either $a$ is a nilpotent or $b$ is a
unit. It is shown that a proper ideal $I$ that is contained in the Jacobson
radical is a quasi $J$-ideal (resp. $J$-ideal) if and only if $R/I$ is a quasi
presimplifiable (resp. presimplifiable) ring.
