In this paper, we aim to prove some new results of Krasnoselskii's fixed point theorem for multivalued operators under weak topology acting in Banach spaces. In particular, the existence of fixed points of multivalued operator L+S is discussed, where L is based on the generalized D-Lipschitzian, S has weakly sequentially closed graph, and I - L may not be injective.
