Abstract:
An electrostatic latent image developing toner includes toner particles each including a toner core and a shell layer disposed over a surface of the toner core. The shell layer includes a plurality of first domains (R1) and a second domain (R2) that is present at least among the first domains (R1). The first domains (R1) are each substantially formed from a first thermoplastic resin. The second domain (R2) is substantially formed from a second thermoplastic resin. The second thermoplastic resin is more hydrophobic than the first thermoplastic resin. The first thermoplastic resin includes at least one specific repeating unit having at least one group selected from the group consisting of a hydroxyl group, an amino group, and an amide group. A proportion of the at least one repeating unit among all repeating units included in the first thermoplastic resin is at least 0.5 mol % and no greater than 50 mol %.
