To provide a toner that can be fixed at a lower temperature and has excellent heat-resistant storage stability and offset resistance. An amorphous polyester resin is obtained by polycondensing an alcohol component containing 80 mol% or more of a propylene oxide adduct of bisphenol and a linear aliphatic dicarboxylic acid component having 4 to 16 carbon atoms. Each containing an aliphatic dicarboxylic acid in an amount of 4.5 mol% to 35.0 mol%, and the crystalline polyester resin contains an aliphatic diol having 6 to 12 carbon atoms and an aliphatic dicarboxylic acid in an amount of 80 mol% or more. The resin obtained by condensation polymerization of the components to be contained, and the colorant contains a compound represented by the following formula (1). (In Formula (1), R 1 , R 2 , and R 3 represent H or an alkyl group having 1 to 5 carbon atoms, and Ar represents an aryl group.) [Selection figure] None |
