TONER

摘要

The toner has a toner particle that contains a binder resin and a wax, wherein the wax is present in domain form in the interior of the toner particle; the proportion of toner particles for which the position of the wax domains are controlled, is in a prescribed range; using d for a major axis length of the domain having the largest major axis length and using D for a number-average particle diameter of the toner, the d and D satisfy a prescribed relationship; and the ratio between the major axis length and the minor axis length of the domain having the largest major axis length is in a prescribed range.

1. A toner comprising a toner particle containing a binder resin and a wax, wherein
in a three-dimensional analysis of the internal structure of the toner particle, (i) the wax is present in domain form in the interior of the toner particle; (ii) the proportion of toner particles for which a shortest distance between a surface of the toner particle and a domain having a largest major axis length among the domains of the wax is less than 50 nm, is equal to or less than 10.0 number %; (iii) the proportion of toner particles for which the shortest distance between the surface of the toner particle and the domain having the largest major axis length is at least 50 nm and not more than 500 nm, is equal to or greater than 60.0 number %; (iv) using d for a major axis length of the domain having the largest major axis length and using D for a number-average particle diameter (D1) of the toner, the d and D satisfy the relationship with the following formula (1)
