| description | To provide a liquid developer having high image density.SOLUTION: A liquid developer contains a toner particle containing a binder resin and a colorant, and an insulating liquid. The binder resin contains an amorphous polyester resin, and an ester compound E that is a polycondensate of an alcohol component containing an alcohol having a valency of 2 or more and a carboxylic acid component containing a monovalent carboxylic acid compound, with an acid value of 0.1 mgKOH/g or more and 15 mgKOH/g or less and a hydroxyl value of 20 mgKOH/g or more and 200 mgKOH/g or less.SELECTED DRAWING: None
