Current flowing through the heating elements make them red hot. Since the elements don't touch the bread, there is no conduction. The mirror-like surface behind the elements and the glowing elements radiate infrared heat (thermal radiation). When the waves hit the bread, it transfers the radiated heat to the bread, drying and heating the surface.
