Résumé : We present recent results on the stellar evolution in cluster galaxies from z~1 to present from the Next Generation Virgo Cluster Survey. Our survey covers 104 sq. deg. centered on the Virgo cluster with deep CFHT/Megacam imaging in five band passes. We detect background clusters with dedicated methods based on the search of red galaxy and photometric redshift overdensities. We analyze galaxy stellar population evolution in clusters from z~1 to present using scaling relations, such as the color-magnitude relation.
