Abstract
An electrostatic latent image developing toner contains a plurality of toner particles each including a toner core and a shell layer disposed over a surface of the toner core. The shell layer has at least one first domain having a film shape and a plurality of second domains each having a particle shape. The first domain is formed substantially from a non-crosslinked resin. The second domains are formed substantially from a crosslinked resin. The crosslinked resin has a glass transition point 45° C. or more greater than the non-crosslinked resin. The first domain has an average height from the surface of the toner core of at least 10 nm and less than 50 nm. The second domains have an average height from the surface of the toner core of at least 50 nm and no greater than 100 nm.

An electrostatic latent image developing toner comprising a plurality of toner particles each including a core and a shell layer disposed over a surface of the core, wherein
- the shell layer has at least one first domain having a film shape and a plurality of second domains each having a particle shape,
- the first domain is formed substantially from a non-crosslinked resin,
- the second domains are formed substantially from a crosslinked resin,
- the crosslinked resin has a glass transition point 45° C. or more greater than the non-crosslinked resin,
- the first domain has an average height from the surface of the core of at least 10 nm and less than 50 nm,
- the second domains have an average height from the surface of the core of at least 50 nm and no greater than 100 nm, and
- a ratio of a region of the core covered with the first domain relative to an entire surface region of the core is at least 40% and no greater than 80%.
