Galaxy clusters provide unique laboratory for the study of galaxy evolution in many aspects. It has been well known that galaxy clusters at high redshift contain larger fraction of star-forming galaxies compared to local massive clusters. In addition, we, in Lee et al. 2015, also have shown that the quiescent galaxy fraction of high redshift galaxy clusters spans a wide range. In this presentation we discuss about this variety in quiescent galaxy fraction of high redshift galaxy clusters and its origin, introducing our new observational results of z~1 clusters.
