A toner is provided including toner particles A having a circularity of greater than 0.93 and not greater than 1.00 and toner particles B having a circularity of from 0.85 to 0.93, wherein the following relationships are satisfied: 70≦RA≦95, 5≦RB≦30, 0.014≦SD≦0.025, and 0.940≦ED≦0.950, wherein RA (% by number) represents a ratio of a number of the toner particles A to a total number of toner particles included in the toner, RB (% by number) represents a ratio of a number of the toner particles B to the total number of toner particles included in the toner, SD represents a standard deviation of circularity of the toner particles A, and ED represents an average envelope degree of the toner particles B.
