Abstract
A toner has a toner particle including a binder resin, a colorant, and a wax, in which in a cross section of the toner particle observed under a scanning transmission electron microscope, a proportion of the number of toner particles having a void with a long diameter of 0.50 μm or less is 60 number % or more, and a proportion of the number of toner particles having a void in a region from an outline of the cross section of the toner particle inward to 1.00 μm in a total number of the toner particles having a void is 30 number % or less.
Claims3
