First claim
Opening claim text (preview).
What is claimed is: 1 . An ultraviolet-curable liquid developer comprising a cationically polymerizable liquid monomer, a photoinitiator, and a toner particle, wherein the cationically polymerizable liquid monomer contains a vinyl ether compound; a molar average SP value of the cationically polymerizable liquid monomer is not more than 9.0; a molar average number of functional groups for the cationically polymerizable liquid monomer is at least 1.8; the photoinitiator contains a compound represented by the following formula (1); and a content of the compound represented by the following formula (1) is at least 0.01 mass parts and not more than 5.00 mass parts per 100 mass parts of the cationically polymerizable liquid monomer, wherein, R 1 and R 2 are bonded to each other to form a ring structure; x is an integer that is at least 1 and not more than 8; and y is an integer that is at least 3 and not more than 17. 2 . The ultraviolet-curable liquid developer according to claim 1 , wherein the content of the compound represented by the formula (1) is at least 0.05 mass parts and not more than 1.00 mass part per 100 mass parts of the cationically polymerizable liquid monomer. 3 . The ultraviolet-curable liquid developer according to claim 1 , wherein the cationically polymerizable liquid monomer comprises a cationically polymerizable liquid monomer that has an SP value of not more than 9.0. 4 . The ultraviolet-curable liquid developer according to claim 1 , wherein the cationically polymerizable liquid monomer comprises a cationically polymerizable liquid monomer that has at least two polymerizable functional groups per one molecule. 5 . The ultraviolet-curable liquid developer according to claim 1 , wherein the compound represented by the formula (1) is a compound represented by the following formula (2) wherein x represents an integer that is at least 1 and not more than 8; y represents an integer that is at least 3 and not more than 17; R 3 and R 4 each independently represent an alkyl group, an alkyloxy group, an alkylthio group, an aryl group, an aryloxy group, or an arylthio group; o and p each independently represent an integer that is at least 0 and not more than 3; when o is equal to or greater than 2, a plurality of R 3 may be bonded to each other to form a ring structure; when p is equal to or greater than 2, a plurality of R 4 may be bonded to each other to form a ring structure; and R 3 and R 4 may be bonded to each other to form a ring structure. 6 . The ultraviolet-curable liquid developer according to claim 1 , further comprising a photopolymerization sensitizer, wherein the photopolymerization sensitizer contains a thioxanthone compound or an anthracene compound. 7 . The ultraviolet-curable liquid developer according to claim 6 , further comprising a photopolymerization sensitizing aid, wherein the photopolymerization sensitizing aid contains a naphthalene compound.
