Abstract
An electrostatic latent image developing toner includes a plurality of toner particles each including a core and a shell layer. The shell layer includes a first domain that is a non-crosslinked resin film and second domains that are crosslinked resin particles. The crosslinked resin has a higher glass transition point than the non-crosslinked resin. In a cross-sectional image of a toner particle, a proportion of a total length of a surface region of the core covered by the first domain is at least 45% and no greater than 80% relative to a circumferential length of the core. In a cross-sectional image of a toner particle, a proportion of second domains adhering to a surface of the first domain is at least 30% by number and no greater than 70% by number relative to all the second domains included in the toner particle.
