Inkjet ink and image forming method

Abstract

An inkjet ink includes a gelling agent and a polymerizable compound that is polymerized by active rays, and the inkjet ink undergoes sol-gel phase transition by the gelling agent. The polymerizable compound includes a first polymerizable compound, wherein the first polymerizable compound includes a benzene ring and further includes one or more ethylene oxide groups and/or one or more propylene oxide groups in a molecule thereof, and the total number of the ethylene oxide groups and the propylene oxide groups is 2 or more; the content of the first polymerizable compound is more than 5% by mass based on the total mass of the inkjet ink; and the gelling agent is a compound that causes the ink to undergo a reversible sol-gel phase transition by a temperature change, and the gelling includes a hydrocarbon group having 22 or less carbon atoms.
