    摘要: The present invention provides a toner for developing an electrostatic latent image which suppresses an adhesion and wearability on a surface of a photosensitive member and exhibits an excellent rising property of an electrification. The toner comprises (i) toner particles containing a binder resin and a colorant, (ii) a first external additive consisting of first inorganic particles whose number-average particle size is 5-40 nm, (iii) a second external additive consisting of second inorganic particles whose number-average particle size, which is larger than that of the first external additive, is 20-160 nm, (iv) a third external additive consisting of third inorganic particles whose number-average particle size, which is larger than that of the second external additive, is 80-1200 nm, and (v) a fourth external additive consisting of a metal salt of fatty acid whose volume-average particle size is 1.5-12 &mgr;m, said four external additives being externally added to the toner particles.

    摘要: A toner used for an image forming method comprises steps of: limiting an amount of toner on a surface of a toner carrier by allowing a toner layer limiting member to be pressed to the surface of the toner carrier; and developing an electrostatic latent image formed on an electrostatic latent image carrier using the toner carried and transferred by the toner carrier, based on a non-magnetic single component development system, wherein the toner comprises toner particles having a volume average particle diameter of 3 to 9 μm, an arithmetic mean value of shape factor of 1.1 to 1.5, a coefficient of variation of shape factor of 16% or less, a ratio of rounded toner particle of 50% by number or more and a coefficient of variation of number particle diameter distribution of 26% or less, and a conveyance index of 2.0 to 10.0.
