Abstract: Provided is an ink composition that includes a color material, water, an organic solvent, and polymer particles, the organic solvent including an organic solvent with a standard boiling point of equal to or greater than 150° C. and equal to or less than 250° C., the content of the organic solvent that is an alkyl polyol with a standard boiling point of equal to or greater than 280° C. being equal to or less than 2.0% by mass with respect to a total amount of the ink composition, the polymer particles having a core-shell structure including core polymer and shell polymer, and a glass transition temperature of the shell polymer being higher than that of the core polymer, and that is used for a recording method using the ink composition and an aggregating liquid containing an aggregating agent capable of aggregating components of the ink composition and increasing viscosity of the components.

Abstract: A printer comprises a main body cover configured to change over a state between a closed state and an open state; a tank including an ink container portion configured to contain ink and an ink inlet configured to inject the ink; a tank cover configured to change over a state between a closed state and an open state; and an ink bottle including a container portion and a delivery portion. In the open state of both the main body cover and the tank cover, the ink bottle is self-supported and configured to deliver the ink from the delivery portion of the ink bottle to the ink inlet. A space is formed between the main body cover and the ink bottle when the ink bottle is self-supported. At least part of the ink bottle is located in a locus drawn by the main body cover during rotation.
