Abstract
The ultraviolet-curable liquid developer contains a hydrophobic cationically polymerizable liquid monomer, a photopolymerization initiator, a toner particle insoluble in the liquid monomer, and a toner particle dispersing agent, wherein the toner particle contains a binder resin that has an acid value of at least 5 mg KOH/g; the toner particle dispersing agent is a polymer that contains at least both a monomer unit represented by general formula (1) and a monomer unit represented by general formula (2); and the toner particle dispersing agent has a monomer unit represented by general formula (1) at a position other than the terminal position.
