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 CH 2 =CR 1 -COOR 2 (where R 1 represents hydrogen or a methyl group; and R 2 represents an alkyl group having 1 to 10 carbon atoms), and the monomer C is CH 2 =CR 3 -COOR 4 (where R 3 represents hydrogen or a methyl group; R 4 represents (CH 2 CH 2 O) n CH 3 or (CH 2 CH 2 O) n CH 2 CH 3 ; and n represents an integer of 12 to 18). |
