Abstract

To provide a toner, containing: a crystalline polyester resin; and a non-crystalline polyester resin, wherein the crystalline polyester resin has a melting point of 60°C to 80°C, and wherein the toner satisfies the relationship represented by the following formula: (W1-W1')/W1<0.50, where W1 is a temperature width at a 1/3 height of a height of an endothermic peak of the crystalline polyester resin at the time of an initial temperature elevation on a DSC curve of the toner as measured by differential scanning calorimetry, and W1' is a temperature width at a 1/3 height of a height of an endothermic peak of the crystalline polyester resin after the toner has been heated at 50°C for 24 hours.
