Using AKARI's continuous wavelength coverage between 3 and 24um and the wide field of view, we investigate the properties of cluster member galaxies to see how the infall of the galaxies, the cluster substructures, and the cluster-cluster merger influence their evolution. We show that the excess of MIR (~11um) flux is a good indicator for discriminating galaxies at different evolutionary stages and for dividing galaxies into three classes accordingly: strong MIR-excess (N3-S11>0.2) galaxies that include both unobscured and obscured star-forming galaxies; weak MIR-excess (-2.0<N3-S11<-1.2) galaxies that are quiescent, old (>5Gyr) galaxies where the MIR emission arises mainly from the circumstellar dust around AGB stars; and intermediate MIR-excess (-1.2<N3-S11<0.2) galaxies in between the two classes that are less than a few Gyr old past the prime star formation activity. With the MIR-excess diagnostics, we investigate how local and cluster-scale environments affect the individual galaxies. We derive the total star formation rate (SFR) and the specific SFR of A2255 using the strong MIR-excess galaxies.2011ApJ...727...14Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/727/14CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/306 : The SDSS Photometric Catalog, Release 8 (Adelman-McCarthy+, 2011)II/297 : AKARI/IRC mid-IR all-sky Survey (ISAS/JAXA, 2010)J/other/JApA/32.567 : Rotation measures in A2255 at 18, 21, 25, 85cm (Pizzo+J/ApJS/149/53 : Multicolor photometry of A2255 galaxies (Yuan+, 2003)J/AJ/124/2453 : Spectroscopy of active galaxies in nearby clusters (Miller+,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/727/14https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/727/14http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/727/14https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/727/14https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/727/14http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/727/14GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/727/14/table2 (AKARI IRC 3-24{mu}m, and Spitzer MIPS 24/70{mu}m photometry of Abell 2255 member galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/727/14/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/727/14/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/727/14/table2?GETtext/xml+votable180.050000true257.4104964.345580.0055555555555555566/11589 11591 115972.4016587514425055e-21 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/727/14?format=asciiOpticalInfrareddefaultJ/ApJ/727/14/table2AKARI IRC 3-24{mu}m, and Spitzer MIPS 24/70{mu}m photometry of Abell 2255 member galaxiesY03Galaxy identification in Yuan et al., 2003, Cat.
