Abstract
Provided is a liquid developer that gives a high image density, has a high resistance, suppresses the appearance of image blurring, can be reused, is readily cured by ultraviolet radiation, and can accommodate higher process speeds. This liquid developer contains a carrier liquid, a toner particle insoluble in the carrier liquid, and a compound with the following formula (1) [In formula (1), R1 and R2 each independently represent an alkyl group having at least 13 and not more than 23 carbons.].
Claims17
A liquid developer comprising:
- a carrier liquid;
- a toner particle that is insoluble in the carrier liquid;
- a compound with formula (1)
- where R1 and R2 each independently represent an alkyl group having 13 to 23 carbons;
- and
- a polymer compound that has a structural unit with formula (2)
- where R3 to R6 each independently represent a hydrogen atom or an alkyl group;
- A represents any of a single bond, carbonyl group, alkylene group, arylene group, or —COOR9— (where the carbonyl group in —COOR9— is bonded to a carbon atom to which R3 is bonded and R9 represents an alkylene having 1 to 4 carbons);
- and B represents an alkylene group or an arylene group, wherein
- the content ratio on a molar basis of the compound with formula (1) to the polymer compound having the structural unit with formula (2) is 5:1 to 35:1.
