Electrostatic latent image developing toner

摘要

An electrostatic latent image developing toner of the present disclosure contains 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 is constituted by a resin containing a thermosetting resin. A zeta potential of the toner core measured in an aqueous medium adjusted to pH 4 is negative, and a zeta potential of the toner particle measured in an aqueous medium adjusted to pH 4 is positive. A pH at which the zeta potential of the toner particle measured in an aqueous medium is zero is 4.5 or higher and 7.0 or lower.
