The toner comprising toner particles having at least a binder resin and a colorant, and inorganic fine particles is characterized in that: toner particles having a circle-equivalent diameter of >=3 [mu]m and <=400 [mu]m of the toner particles measured by a flow type particle image analyzer have an average circularity of >=0.935 and <0.970; the toner particles have an average surface roughness of >=5.0 nm and <35.0 nm measured by a scanning probe microscope; and the binder resin contains at least a vinyl resin having a carboxyl group and a vinyl resin having a linkage as a partial structure formed by the reaction of a carboxyl group with an epoxy group.
