Annealing effect on magnetic properties of superconductivity is investigated for the crystals of Bi1.9CaySr1.9-yCuO6+\delta ($0\leq y\leq 1.8$) in Bi-2201 phase. It is found that carrier density is reduced with Ca doping in Ca-poor region of $y\leq 0.8$. In contrast, the excess oxygen $\delta$ is saturated with doping at about the optimal $T_{\text{c}}$ in Ca-rich region of $y>0.8$. The results indicate possible oxygen deficiencies with Ca doping, which gives a new aspect to a model for the appearance of 80 K-class superconductivity.
