Abstract
An ink set includes an inkjet ink and a cleaning solution. The inkjet ink contains a first aqueous medium, a carbon black, a dispersing resin, a first zwitterionic surfactant having an amidoalkylbetaine structure, and a first sugar alcohol. The carbon black has an oil absorption number of at least 130 mL/100 g and no greater than 165 mL/100 g. A ratio of a content of the dispersing resin to a content of the carbon black is at least 12.0% by mass and no greater than 19.0% by mass. The cleaning solution contains a second aqueous medium, a second zwitterionic surfactant having an amidoalkylbetaine structure, and a second sugar alcohol.
