PROBLEM TO BE SOLVED: To provide a toner that achieves low-temperature fixability, offset resistance, heat resistant storage stability, excellent dispersibility of pigments, and stain resistance on developing rollers and the like, and to provide a developer. SOLUTION: A binder resin in the toner comprises: a polyester resin (A) which is produced by polycondensing an alcohol component with a carboxylic acid component which contains a rosin compound in an amount of 5% by mass or more of the total amount by mass of the alcohol component and carboxylic acid component; and a polyester resin (B) which is produced by polycondensing an alcohol component containing an alkylene oxide adduct of bisphenol A represented by General Formula (1) with a carboxylic acid component, and the toner contains abietic acid in an amount of 0.01% by mass to 1% by mass: where R<SB>1</SB>and R<SB>2</SB>each represent a C2-C4 alkylene group; R<SB>3</SB>and R<SB>4</SB>are each any one of a hydrogen atom, a C1-C6 straight-chain alkyl group, and a C1-C6 branched-chain alkyl group; and x and y each represent a positive integer and the sum of x and y is 1 to 16.
