| 发明名称 | Electrostatic latent image developer | ||
| 摘要 | An electrostatic latent image developer of the present invention includes a resin, a colorant and a colorant dispersant, wherein the colorant dispersant contains a first polymer compound containing a constitutional unit derived from a monomer A, a constitutional unit derived from a monomer B and a constitutional unit derived from a monomer C, the monomer A is 4-vinylpyridine, the monomer B is CH2═CR1—COOR2 (where R1 represents hydrogen or a methyl group; and R2 represents an alkyl group having 1 to 10 carbon atoms), and the monomer C is CH2═CR3—COOR4 (where R3 represents hydrogen or a methyl group; R4 represents (CH2CH2O)nCH3 or (CH2CH2O)nCH2CH3; and n represents an integer of 12 to 18). | ||
