Abstract
An electrostatic latent image developing toner includes toner particles. Each toner particle includes a toner core containing a binder resin, a shell layer coating a surface of the toner core, and needle-like inorganic particulates. Each shell layer contains a thermosetting resin, and the inorganic particulates are present within the shell layer. The inorganic particulates have: an aspect ratio of 1.25 or more and 2.5 or less; and an average major diameter and an average minor diameter of 300 nm or less.
Claims10
A method for manufacturing an electrostatic latent image developing toner, comprising:
- preparing toner cores containing a binder resin;
- causing needle-like inorganic particulates to adhere to the respective toner cores;
- and
- forming shell layers to coat surfaces of the respective toner cores and the inorganic particulates, wherein
- the shell layers contain a thermosetting resin, and
- the needle-like inorganic particulates are present between the toner cores and the shell layers, the inorganic particulates having
- an aspect ratio of 1.25 or more and 2.5 or less, and
- an average major diameter and an average minor diameter of 15 nm or more and 300 nm or less.
