A photocurable ink contains a polymerizable compound and a photopolymerization initiator, and this ink contains a low boiling point solvent having a boiling point of 40&#xb0; C. to 120&#xb0; C. at one atmospheric pressure and at least one particle having a surface on which an unsaturated hydrocarbon group is provided.

Photocurable ink, ink container, and image forming method

A photocurable ink containing a first liquid containing a polymerizable compound and a photopolymerization initiator, and a second liquid that is incompatible with the first liquid, in which droplets formed by the second liquid are dispersed in the first liquid, wherein the photocurable ink contains first particles and second particles having higher hydrophilicity than that of the first particles, wherein the first particles are adsorbed on an interface between the first liquid and the second liquid, and the second particles are present in the second liquid.

A photo-curable ink contains an oil-based liquid containing a polymerizable compound and a photopolymerization initiator, and an aqueous liquid containing water. When the photo-curable ink is stirred at a rotational speed of 15000 rpm or more for 3 minutes and then allowed to stand at 25&#xb0; C. for one hour or more, droplets formed with the aqueous liquid are dispersed in the oil-based liquid without layer separation between the oil-based liquid and the aqueous liquid.
