Abstract:
An electrostatic latent image developing toner includes a plurality of toner particles each including a toner core and a shell layer. The shell layer includes a plurality of first shell particles and a plurality of second shell particles. The first shell particles cover the toner core at a coverage of at least 25% and no greater than 50%. The second shell particles additionally cover the toner cores at a coverage of at least 5% and no greater than 30%. An SP value of the toner core is greater than an SP value of the first shell particles. The SP value of the first shell particles is greater than an SP value of the second shell particles.
