a colorant; and
at least one of a compound represented by formula 1, a compound represented by formula 2, a compound represented by formula 3, or a compound represented by formula 4,

where R 1 represents a cycloalkyl group having 1 to 10 carbon atoms, an aryl group having 1 to 10 carbon atoms, or an aralkyl group having 1 to 10 carbon atoms, and
R 2 represents a monovalent group comprising a group represented by —OX 1 , where X 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —COOX 2 , where X 2 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —OCOX 3 , where X 3 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —NX 4 X 5 , where X 4 and X 5 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —CONX 6 X 7 , where X 6 and X 7 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, or a monovalent group comprising a hydroxyl group,

where, R 3 and R 4 each, independently represent monovalent groups comprising groups represented by —OX 1 , where X 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —COOX 2 , where X 2 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —OCOX 3 , where X 3 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —NX 4 X 5 , where X 4 and X 5 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —CONX 6 X 7 , where X 6 and X 7 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, or a monovalent group comprising a hydroxyl group,

where a ring A represents a saturated five-membered ring or a saturated six-membered ring, both having one nitrogen atom in the ring structure, R 5 represents a monovalent group comprising a group represented by —OX 1 , where X 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —COOX 2 , where X 2 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —OCOX 3 , where X 3 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —NX 4 X 5 , where X 4 and X 5 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —CONX 6 X 7 , where X 6 and X 7 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, or a monovalent group comprising a hydroxyl group, and a is 1, 2, or 3, and

where a ring B represents a saturated five-membered ring or a saturated six-membered ring, both comprising two nitrogen atoms, R 6 represents a monovalent group comprising a group represented by —OX 1 , where X 1 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —COOX 2 , where X 2 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —OCOX 3 , where X 3 represents a monovalent hydrocarbon group having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —NX 4 X 5 , where X 4 and X 5 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a group represented by —CONX 6 X 7 , where X 6 and X 7 each, independently represent monovalent hydrocarbon groups having 1 to 10 carbon atoms, a monovalent group comprising a hydroxyl group, or an alkyl group having 1 to 10 carbon atoms, and
wherein, in formula 4, the nitrogen atom of ring B bound to R 6 is bound to R 6 through a —(CH 2 ) m — linker group, where m represents an integer of from 1 to 6.

2. The ink according to claim 1 , wherein R 2 represents a group represented by formula 5

3. The ink according to claim 1 , wherein each of R 3 and R 4 represents a group represented by formula 5

4. The ink according to claim 1 , wherein the compound represented by formula 3 is represented by formula 6

5. The ink according to claim 4 , wherein R 5 is a group represented by —COOX 2 , where X 2 represents a hydrocarbon group having 1 to 10 carbon atoms.

6. An ink cartridge comprising:
the ink of claim 1 ; and
a container to accommodate said ink.

7. An ink jet recording device comprising:
a discharging device comprising the ink of claim 1 to discharge the ink of claim 1 .

8. An ink jet ink printed matter comprising:
