Abstract
Provided are gel particles each having a three-dimensional crosslinked structure having at least one bond selected from a urethane bond and a urea bond, the gel particles each including: a maleimide group represented by Formula 1 below, a photosensitive composition, an ink composition, a method of producing water dispersion of gel particles, and an image forming method. In Formula 1, R1 and R2 each independently represent a hydrogen atom or an alkyl group, R1 and R2 may be bonded to each other to form a ring, and * represents a bonding site.
