The author is concerned with a generalized integral equation of the form

in the space of continuous functions. The operator $V$ will define a contraction $\tilde{V}$, while the operator $S$ is assumed to be compact. The existence problem is then reduced to finding fixed points for the mapping $Px=\tilde{S}x+(I-\tilde{V})x$. The implicit function theorem and classical fixed point theorems (Schauder, Krasnoselskij) are the tools used by the author in obtaining two fixed point theorems, the first of the type of contraction mapping and the second of Krasnoselskij type (for the sum of two operators). He then applies them to the generalized integral equation considered. Many known results can be derived from the Theorem 3 in this paper. Some examples are provided.
