Electrostatic latent image developing toner
Abstract:
The present disclosure relates to an electrostatic latent image developing toner containing a toner particle including a toner core containing a binder resin and a shell layer coating a surface of the toner core. The shell layer contains a unit derived from a monomer of a thermosetting resin, and a unit derived from a thermoplastic 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 toner particle contains fine particles in an interfacial portion between the toner core and the shell layer, and the fine particles have a charge property opposite to that of the toner, or have a volume resistivity lower than both a volume resistivity of the binder resin and a volume resistivity of the shell layer.
