• We present the results of an infrared (IR) study of high-redshift galaxy clusters with the MIPS camera on board the Spitzer Space Telescope. We have assembled a sample of 42 clusters from the Red-Sequence Cluster Survey-1 over the redshift range 0.3 < z < 1.0 and spanning an approximate range in mass of 10 super(14-15) M sub([middot in circle]). We statistically measure the number of IR-luminous galaxies in clusters above a fixed inferred IR luminosity of 2 x 10 super(11) M sub([middot in circle]), assuming a star forming galaxy template, per unit cluster mass and find it increases to higher redshift. These results are tied to the adoption of a single star forming galaxy template; the presence of active galactic nuclei, and an evolution in their relative contribution to the mid-IR galaxy emission, will alter the overall number counts per cluster and their rate of evolution.
