Abstract:
A toner for use in the development of electrostatic latent images contains colored particles including at least a binder resin, a coloring agent and a releasing agent, and an external additive. An average circularity of the toner is 0.975 or more; a median of arithmetic average height distribution of the toner is 0.05 μm or more and not more than 0.12 μm; and a fluctuation of arithmetic average height is not more than 35. Preferably, a value of 90% accumulation of the arithmetic average height distribution of the toner is less than 0.15 μm; and a fluctuation of number average particle size and a fluctuation of circularity of the toner are not more than 25 and not more than 2.5, respectively. The electrostatic latent image developer contains the foregoing toner and a carrier, and the image forming method uses the foregoing toner or the foregoing developer.
