Ink, ink set and printer

A printing apparatus comprising:

• an ink ejector configured to eject an ink to an object on which a printed record is to be produced;
• a dryer;
• and
• a melting device, wherein
• the ink comprises:
• a medium;
• a coloring agent dissolved or dispersed in the medium;
• a fixing polymer having a glass-transition temperature higher than room temperature and being dispersed in the medium;
• and
• one or more kinds of polymers other than the fixing polymer, the one or more kinds of polymers each having a glass-transition temperature higher than the room temperature and being dissolved or dispersed in the medium,
• a glass-transition temperature of the fixing polymer is higher than the glass-transition temperature of 80 mass % or more of the one or more kinds of polymers contained in the ink,
• the dryer is configured to heat the object to expedite evaporation of the medium,
• the melting device is configured to subject the ink on the object to heat that causes the fixing polymer to melt and to fix the ink to the object accordingly, and
• the melting device irradiates the ink on the object with ultraviolet rays to heat the ink and melt the fixing polymer while the ink is exposed to a surrounding atmosphere.
