 ABSTRACT = {The present paper examines models for the expected contribution to
             the X-ray background (XRB) from clusters of galaxies in a flat
             universe with a spectrum of fluctuations corresponding to the
             standard cold dark matter picture and for a power-law spectrum
             $P(k)$ varies as $k^n$ with $n = -2$. A self-similar scaling model
             for clusters proposed by Kaiser (1986) is presented, along with
             several variants. Photon statistics from synthesized maps of deep
             Einstein fields show a granularity similar to that deduced by
             Hamilton and Helfand (1987) from the Einstein data but overproduces
             by a large factor the number of discrete sources observed as
             clusters, and the fluctuation limit derived from the recent
             correlation analyses of the background. Two alternative models are
             designed to be consistent with the local luminosity function data;
             for these, expected deep images for the Rosat satellite are
             generated. Clusters of galaxies should be a significant source of
             background at energies around 2 keV, and it is proposed that
             clusters of galaxies contribute up to 30 percent of the unresolved
             component.},
