2009
The present invention provides the fluidity, chargeability and fixability improving toner, developer, developing apparatus and an image forming apparatus. The toner comprising the core particle surface is formed a shell of the toner particles and the external additive (1) is formed in the shell of the core particle surface film, (2) a shape factor SF-2 of 120 or more, 140 or less, ( . 3) as measured by the BET BET specific surface area of 1.2m2 / cm3 or more, 4.0m2 / cm3 or less. The developer containing the toner is filled in the developing apparatus of the image forming apparatus, an image is formed.
