titleOfInvention | Image forming apparatus |
abstract | [PROBLEMS] To secure a stable developer carrying amount under a developing condition with a small doctor gap accompanying proximity development, maintain a high developing ability over a long period of time, obtain a sufficient image density, and cause unevenness in image density. There is provided an image forming apparatus capable of developing faithfully to a latent image. A developing device 424 includes a developing roller 442 that carries a two-component developer and a developer regulating member 443, and a developing gap between the developing roller and the image carrier is 0.05 to 1.0 to mm. The amount of developer carried in the development area is 20 to 50 mg / cm 2 , the toner contains at least a binder resin and a colorant, and an external additive is added to the surface. , A magnetic carrier in which a coating layer is formed on the surface of a core material having a BET specific surface area of 400 to 800 cm 2 / g, and a fluidity index value FT of a toner obtained by a conical rotor method and a fluidity index of a two-component developer The ratio of the value FD (FD / FT) satisfies 1.5 ≦ FD / FT ≦ 3.5.
