It comprises both a at least one phthalocyanine compound expressed by general formula (1) and a at least one phthalocyanine compound expressed by general formula (2):
where, in the general formulae (1) and (2),
M
1
represents at least one arbitrary atom or atomic group that is capable of binding to a phthalocyanine,
M
2
represents an atom, or an atomic group containing an atom, selected from the second and subsequent periods of the periodic table and capable of binding to a phthalocyanine, M
1
and M
2
being different in kind from each other,
X
1
-X
4
represent, independently of each other, a halogen atom, and
a, b, c, and d represent, independently of each other, an integer between 0 and 4 and satisfy
