  • Publication number: 20090180809
    Abstract: A toner is so configured as to satisfy the following conditions: (b)/(a) is from 0.90 to 1.02, (a) is from 140 to 150 and the average value in the entire toner particles of a shape factor SF-2 of the toner particles is larger than 140, where (a) represents a shape factor SF-2 showing the degree of irregularity on the surface of toner particles having a particle size D75V or less which is a particle size at which a cumulative volume from a large particle size side in particle size distribution by volume is 75%, and (b) represents a shape factor SF-2 of toner particles having a particle size D25V or more which is a particle size at which a cumulative volume from a large particle size side in particle size distribution by volume is 25%.

  • Publication number: 20090098475
    Abstract: There are provided a toner, a method of manufacturing the toner, a two-component developer, a developing device, and an image forming apparatus, which are excellent in a charge rising property, environmental stability, and life stability during printing and which cause less fogging. The toner contains a core particle containing binder resin and colorant, and a coating layer which contains resin and a charge control agent and is formed on a surface of the core particle. At least a part of the resin contained in the coating layer is melt-bonded to the core particle, and the charge control agent is dispersed and immobilized in the coating layer. The dispersed charge control agent has a dispersion diameter of less than 1 ?m.

  • Publication number: 20090004590
    Abstract: in a toner at least containing a binder resin and a colorant, a value obtained by dividing a particle size D50p by a particle size D84p is 1.43 or more and 1.64 or less, wherein D50p and D84p respectively represent particle sizes at 50% and 84% of cumulative number counted from a large-size side in a cumulative number distribution. Further, in the toner, an average degree of circularity of toner particles having a volume average particle size of 1 ?m or more and 4 ?m or less is 0.940 or more and 0.960 or less. Further, in the toner, a content of toner particles having an average degree of circularity of 0.850 or less is 10% by number or less among the toner particles having a volume average particle size of 1 ?m or more and 4 ?m or less.
