Based on the morphological classification for 290 member galaxies in the neaby galaxy cluster Abell 2199, relations of the star formation rates (SFRs) with morphology and relevant physical properties of cluster galaxies are studied. A tight correlation between the SFR normalized by stellar mass (SFR/M*) and the Hα equivalent width is found. The correlations of SFR/M* with the continuum break strength at 4000Å and stellar mass (M*) are also confirmed. Recent finding of a significant substructure near the central cD galaxy indicates Abell 2199 possesses a group merger. These cluster galaxies show no significant environmental effect in their star formation activities, which suggests that Abell 2199 is still at an active stage of dynamical evolution, far from a state of dynamical equilibrium.
