PROBLEM TO BE SOLVED: To provide a toner capable of obtaining an image maintaining high image quality, particularly high transferability even when used for a long time. In a toner containing at least colored particles having a binder resin and a colorant and inorganic fine particles (A), (i) the binder resin contains at least a polyester unit, and (ii) an equivalent circle diameter of 2 μm or more. The toner particles have an average circularity of 0.915 to 0.960, and (iii) the inorganic fine particles (A) have an aspect ratio (major axis / minor axis ratio) of 1.0 to 1 on the toner surface. The number average particle size on the toner surface is 0.06 to 0.30 μm. [Selection figure] None |
