Abstract:
An electrostatic latent image developing toner of the present invention includes toner base particles and particles containing a fatty acid metal salt. The toner base particles contain a crystalline resin containing a segment of a first resin and a segment of a second resin chemically bonded to each other and an amorphous resin containing at least the second resin. The crystalline resin is a hybrid crystalline polyester resin. The first resin is a crystalline polyester resin. The second resin is an amorphous resin. The volume-based median diameter (Da) of the toner base particles and the volume-based median diameter (Db) of the particles containing the fatty acid metal salt satisfy the relations represented by Expressions (1) and (2) below: 0.5 μm≦Db≦2.0 μm Expression (1) 0.1 Db/Da≦0.5. Expression (2)
