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<=R<SUB>A</SUB><=95, 5<=R<SUB>B</SUB><=30, 0.014<=SD<=0.025, and 0.940<=ED<=0.950, WHEREIN R<SUB>A </SUB>(% by number) represents a ratio of a number of the toner particles A to a total number of toner particles included in the toner, R<SUB>B </SUB>(% 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.
