In this paper we study the strong gravitational lensing scenario where the lens is a Reissner-Nordström black hole. We obtain the basic equations and show that, as in the case of a Schwarzschild black hole, in addition to the primary and secondary images, two infinite sets of relativistic images are formed. We find analytical expressions for the positions and amplifications of the relativistic images. The formalism is applied to the case of a low-mass black hole placed at the galactic halo.
