The Press-Schechter formalism is used to derive the abundance of rich galaxy clusters in dependence on the cluster mass or the corresponding X-ray temperature of the hot gas confined in the cluster potential wells. We consider a characteristic double inflation spectrum in the standard CDM model leading to a hierarchical clustering scenario. Normalising the amplitude to the COBE-quadrupole, and supposing a biasing b ≈ 2, we get a reasonable fit both to the amplitude and the slope of the X-ray temperature function of Edge et al. (1990) and Henry & Arnaud (1991). In the considered model the cluster abundance changes strongly with redshift.
