Abstract. The aim of this paper is to obtain new univalence criteria for integral operators which were introduced by N. N. Pascu and S. Moldoveanu. The improvement consists in the fact that the new hypothesis are more simple, that is they do not contain |z|. On this reason these can be easily applicated.
