We have incorporated the description of the X-ray properties of Active Galactic Nuclei AGNs into a semi-analytic model of galaxy formation, adopting physically motivated scaling laws for accretion triggered by galaxy encounters. Our model reproduces the level of the cosmic X-ray background at 30 keV; we predict that the largest contribution around 2-3 comes from sources with intermediate X-ray luminosity 10^{43.5} L X-erg-s
