In this paper, the author combines the topological degree theory and the monotone iterative technique to investigate the existence of solutions and also minimal and maximal solutions of the initial value problem for nonlinear integrodifferential equations of mixed type in Banach space. Two main theorems are obtained and two examples are given.
