PROBLEM TO BE SOLVED: To obtain an image having excellent image storage stability such as fixability, light resistance and the like and high density and high sensitivity by providing at least one of dyes represented by formulae (I) to (III) on a support. SOLUTION: At least one type of dyes represented by formulae (I) to (III) are provided on a support, where RA1 , RA2 and RA3 are each hydrogen atom or substituent, =A- is =N- or =LA1 -(LA2 =LA3 )m - group, B is azo group, Q is nonmetallic atom group necessary to form dye having an absorption band in a visible range and/or infrared range, LA1 , LA2 and LA3 are each methine group which may have a substituent, and m is 0, 1 or 2. As the substituents represented by the RA1 , RA2 and RA3 , specifically, halogen atom, alkyl group, or the like is each used. Further, these may each have a substituent. The RA1 , RA2 and RA3 may be the same or different. |
