ABSTRACT:
A toner is composed of toner particles including toner base particles containing at least a binder resin and a colorant, and inorganic fine particles. The toner base particles having a specific circle-equivalent diameter as measured with a flow type particle image analyzer have a specific average circularity. The toner base particles have a specific surface roughness as measured with a scanning probe microscope. The binder resin contains at least a vinyl resin having as partial structure a linkage formed by the reaction of a carboxyl group with an epoxy group.
