We have been investigating the formation and evolution of clusters of galaxies from low redshift to high redshift using the NIR/MIR images taken with the AKARI/IRC, as part of the AKARI mission program: CLEVL. We present an infrared view of these clusters. It is found that the cluster galaxies detected in MIR are divided into two groups: MIR-blue galaxies with (N3-S11)<0 and MIR-red galaxies with (N3-S11)>0 . MIR-red galaxies are star forming galaxies with varying star formation rates, corresponding to late type galaxies. MIR-blue galaxies are red sequence galaxies with varying stellar ages or with low-level star formation activity. The fraction of the MIR-red galaxies varies significantly from cluster to cluster.
