  In a previous paper (Henri & Petrucci, hereafter paper I), we have derived a
new model in order to explain the UV and X-ray emission of radio quiet AGNs.
This model assumes that a point source of relativistic leptons (e+,e-)
illuminates the accretion disk of the AGN by Inverse Compton process. This disk
is supposed to be simply represented by a finite slab which radiates only the
energy reprocessed from the hot source. The radiation field within the hot
source region is therefore highly anisotropic, which strongly influences the
Inverse Compton process. The different Eddington parameters characterizing the
radiative balance of this system have been calculated self-consistently in the
Newtonian case (paper I) giving a universal spectrum for a given inclination
angle. In this paper, we take into account relativistic effects by including
the gravitational redshift, the Doppler boosting and the gravitational focusing
due to the central supermassive black hole. This has the effect of modifying
the radial temperature profile in the innermost region of the disk (at some
gravitational radii). However, the spectrum is hardly different from that
obtained in the Newtonian case, unless the hot source is very close to the
black hole. These results are clearly different from standard accretion disk
models where the gravitational energy is mainly released in the vicinity of the
black hole.
