Abstract
An ink contains a medium, a coloring agent, a fixing polymer, and one or more kinds of polymers other than the fixing polymer. The coloring agent is dissolved or dispersed in the medium. The fixing polymer has a glass-transition temperature higher than the ordinary temperature and is dispersed in the medium. The one or more kinds of polymers each have a glass-transition temperature higher than the ordinary temperature and are dissolved or dispersed in the medium. The fixing polymer is higher in glass-transition temperature than 80 mass % or more of the one or more kinds of polymers contained in the ink and each having a glass-transition temperature higher than the ordinary temperature.
