A liquid developer comprising:
- magnetic polymer particles including a magnetic material containing yttrium iron garnet (YIG), a polymer compound having a carboxylate salt structure, and a colorant;
- and
- a dispersion medium in which the magnetic polymer particles are dispersed.
A method for producing a liquid developer, comprising:
- aggregating a magnetic material containing yttrium iron garnet (YIG), a polymer compound having a carboxyl group, and a colorant in an emulsified liquid to form aggregated particles;
- neutralizing the aggregated particles to obtain magnetic polymer particles;
- and
- dispersing the magnetic polymer particles in a dispersion medium.
