An amorphous polyester resin is provided that includes a polycondensation product of an alcohol component and a carboxylic acid component. The alcohol component includes at least one selected from the group consisting of plant-derived 1,3-propanediol, plant-derived 1,3-butanediol, and plant-derived ethylene glycol, and the carboxylic acid component includes a polycarboxylic acid having a sulfo group. A ratio (OHVa/AVa) of a hydroxyl value (OHVa) of the amorphous polyester resin with respect to an acid value (AVa) of the amorphous polyester resin is from 1.1 to 1.5.
