| abstract | (57) [Problem] To provide a two-component developing type developing device that narrows a developing area to obtain a good image excellent in reproducibility of an ultra-high-resolution image even when a magnetic toner is used. A developing device (2) using a developer (3) having a magnetic toner (3a) has a developing magnetic pole (P1) inside a developing sleeve (4), and the normal magnetic flux density (Bn) generated outside the developing sleeve surface by the developing magnetic pole is attenuated. The ratio is configured to be 50% or more. The magnetic toner of the developer used in this developing device has a weight average particle diameter of 6.0 to 8.0 μm. m, particles having a particle size of 5 μm or less are 40 to 80% by number, and a magnetization intensity in a 5 k Oersted magnetic field is 10 to 25 emu / g; A magnetic toner that satisfies the condition of 7 to 20 emu / g in the magnetic field of 1 k Oersted magnetic field is used. As a result, it is possible to suppress toner scattering, prevent image quality deterioration such as trailing edge white spots, and improve image reproducibility of ultra-high resolution. |
