Electrostatic latent image developing toner and manufacturing method therefor
Abstract:
An electrostatic latent image developing toner includes a plurality of toner particles each having a toner core, a shell layer, and needle-like particles. The needle-like particles adhere to a surface of the toner core. The shell layer contains a thermosetting resin and covers the needle-like particles and the toner core. The needle-like particles contain titanium oxide. The needle-like particles have a volume resistivity value of at least 1.0×101 Ω·cm and no greater than 1.0×108 Ω·cm. The needle-like particles have a number average major-axis diameter of at least 0.2 μm and no greater than 2.0 μm. The needle-like particles have a number average minor-axis diameter of at least 0.01 μm and no greater than 0.10 μm.
