Abstract
In an ink composition, a coloring agent, a color developer, and a decolorization agent are dissolved or dispersed in a solvent. The ink is capable of being colored at 40° C. or less, with the coloring agent reacting with the color developer to form a bonded structure, and also capable of being decolorized when heated to 100° C. or more, with the bonded structure being ruptured to liberate the color developer therefrom, and the liberated color developer being chemically bonded to the decolorization agent. An ink jet printer is provided with a paper feeder for feeding a recording sheet for ink jet printing, a recorder for recording an ink image on the recording sheet fed from the paper feeder using the above-mentioned ink composition, and a paper discharger for discharging the recording sheet from the ink jet printer. By further providing an eraser, the ink image recorded on the recording sheet by the recorder can be erased, thereby achieving recycling of the recording sheet.
