Dispersant having excellent solubility in solvent, adsorptive power to color material, and dispersibility of color material, and reduced self-coloring property, and compound and polymerizable compound for preparing the dispersant, And a toner using the dispersant. A dispersant having a structure in which a structure represented by the following formula (3) and a tautomer thereof are bonded to a polymer, and a toner containing the dispersant. In formula (3), X2, Y2, and Z2 are each independently any of -O-, a methylene group, and -NR10-, and R10 is hydrogen or a linear or branched alkyl group having 1 to 4 carbon atoms. , R7 is a substituted or unsubstituted phenyl group, a polycyclic aromatic group, or a heterocyclic group, R8 is a hydrogen atom, a substituted or unsubstituted phenyl group, an aralkyl group, a straight chain having 1 to 18 carbon atoms, branched or R9 represents a substituted or unsubstituted phenylene group, a linear, branched or cyclic alkylene group having 1 to 18 carbon atoms, and W3 represents a connecting portion with a polymer.
