A toner comprising: a first binder resin; a colorant; a releasing agent; and a crystalline organic compound, wherein the first binder resin contains an amorphous polyester resin (a) having a polyhydroxycarboxylic acid skeleton derived from optically active monomers in a part of a main chain of the amorphous polyester resin, and the polyhydroxycarboxylic acid skeleton has an optical purity X, calculated on the monomer basis, of 80% or less, and the optical purity X is determined from the following equation, Optical Purity X % = X ⁢ L - form - X ⁢ D - form where X (L-form) represents, calculated on the monomer basis, an L-form ratio (mol%), and X (D-form) represents, calculated on the monomer basis, a D-form ratio (mol%), and wherein the crystalline organic compound is any one of a crystalline polyester resin (b) and a crystalline low molecular compound which has a melting point of 60°C to 100°C, and is selected from a group consisting of fatty acid having 16 to 24 carbon atoms, alcohol having 16 to 24 carbon atoms, a fatty acid ester compound, and aliphatic carboxylic acid amide, characterized in that the toner satisfies the following formula: 0 ≤ Q ⁢ 2 / Q ⁢ 1 ≤ 0.30 where Q1 is an endotherm of a melting peak derived from the crystalline organic compound when a temperature of the toner is increased from 20°C to 150°C at a temperature increasing rate of 10°C/min in a first temperature increase, and Q2 is an endotherm of a melting peak derived from the crystalline organic compound when, after the first temperature increase, the temperature is dropped to 0°C at a temperature decreasing rate of 10°C/min, followed by increasing to 150°C at a temperature increasing rate of 10°C/min in a second temperature increase, in DSC measurement of the toner. a first binder resin; a colorant; a releasing agent; and a crystalline organic compound, wherein the first binder resin contains an amorphous polyester resin (a) having a polyhydroxycarboxylic acid skeleton derived from optically active monomers in a part of a main chain of the amorphous polyester resin, and the polyhydroxycarboxylic acid skeleton has an optical purity X, calculated on the monomer basis, of 80% or less, and the optical purity X is determined from the following equation, Optical Purity X % = X ⁢ L - form - X ⁢ D - form where X (L-form) represents, calculated on the monomer basis, an L-form ratio (mol%), and X (D-form) represents, calculated on the monomer basis, a D-form ratio (mol%), and wherein the crystalline organic compound is any one of a crystalline polyester resin (b) and a crystalline low molecular compound which has a melting point of 60°C to 100°C, and is selected from a group consisting of fatty acid having 16 to 24 carbon atoms, alcohol having 16 to 24 carbon atoms, a fatty acid ester compound, and aliphatic carboxylic acid amide, characterized in that the toner satisfies the following formula: 0 ≤ Q ⁢ 2 / Q ⁢ 1 ≤ 0.30 where Q1 is an endotherm of a melting peak derived from the crystalline organic compound when a temperature of the toner is increased from 20°C to 150°C at a temperature increasing rate of 10°C/min in a first temperature increase, and Q2 is an endotherm of a melting peak derived from the crystalline organic compound when, after the first temperature increase, the temperature is dropped to 0°C at a temperature decreasing rate of 10°C/min, followed by increasing to 150°C at a temperature increasing rate of 10°C/min in a second temperature increase, in DSC measurement of the toner.
