We investigate the ideal structures of the C*-algebras arising from topological graphs. We give a complete description of ideals of such C*-algebras that are invariant under the so-called gauge action, and give a condition on topological graphs so that all ideals are invariant under the gauge action. We get conditions for our C*-algebras to be simple, prime or primitive. We completely determine the prime ideals, and show that most of them are primitive. Finally, we construct a discrete graph for which the associated C*-algebra is prime but not primitive.
