We report a study on the loading of a Rb dark magneto-optical trap from a current-controlled getter source. The effect of changing the temperature and number density of the background atoms on the cold atomic population in the dark state has been investigated by passing current of different magnitudes through the getter source. We observe that the dark state collection rate of the cold atoms is maximized for an optimum value of the getter current used. In our experiments, cold atoms in the dark state have been collected with the maximum collection rate 3.6• 107 atoms per second and background atom collision rate \gamma= 1.9\pm 0.2 s-1 for the getter current \sim 4 A.
