Abstract
An electrostatic latent image developing toner includes toner particles each including a toner core containing a binder resin and a shell layer on a surface of the toner core. The shell layer includes a unit derived from a monomer of a thermosetting resin. The thermosetting resin is one or more resins selected from the group of amino resins consisting of a melamine resin, a urea resin, and a glyoxal resin. The inorganic particles intervene in an interface between the toner core and the shell layer. The inorganic particles have a number average particle diameter of 60 nm or more and 250 nm or less. Protrusions having a shape that follows a shape of the inorganic particles are on surfaces of the toner particles.
