1. An ink jet ink composition comprising:
a photopolymerization initiator comprising a plurality of different compounds in a combination of two or more;
a polymerization inhibitor;
a surfactant;
a monomer A that is a radical-polymerizable monomer represented by formula (A):

OG Complex Work Unit Chemistry
where R1 to R4 each independently represent a hydrogen atom or an organic group having 1 to 10 carbon atoms, the organic group being an alkyl group, an alkenyl group, an aryl group, or an aralkyl group, n represents an integer of 1 to 3, and when n is 2 or 3, two or three R3's may be the same or different, and two or three R4's may be the same or different;
a monomer B that is a radical-polymerizable monomer including an alicyclic structure and not including a heterocyclic structure; and
a monomer C that is a radical-polymerizable monomer including a heterocyclic structure and a (meth)acryloyl group,
wherein a total content of the monomer A, the monomer B, and the monomer C is 60 mass % or more relative to a total amount of the ink jet ink composition,
wherein a content of the monomer A is 10 mass % to 30 mass % relative to the total amount of the ink jet ink composition,
wherein a content of the monomer B is 20 mass % to 40 mass % relative to the total amount of the ink jet ink composition,
wherein a content of the monomer C is 20 mass % to 40 mass % relative to the total amount of the ink jet ink composition, and
wherein the ink jet ink composition exhibits a curability such that, when a transfer substrate is peeled off of a solid image of a cured film of the ink jet ink composition after one day has elapsed, a transfer area is less than 25%, the transfer area being a proportion of an area of image transferred to the transfer substrate with respect to a total area of contact between the transfer substrate and the solid image.
