Even when a large-capacity process cartridge with increased process speed or increased toner filling amount in a developing unit is used, image quality such as blotch and fog, deterioration in developability, photoreceptor damage, Provided are a magnetic toner, an image forming method, and a process cartridge that can suppress scattering of the magnetic toner in the machine. A regulating blade that regulates the toner layer thickness of a toner carrier comprising a plurality of magnetic poles in a developing sleeve and that is arranged in a non-rotating manner is provided at a portion of the regulating blade that comes into contact with the toner carrier. The ten-point average roughness Rz of the surface is 5.0 μm or more and 25.0 μm or less, and a magnetic force (peak) acting in the direction of the developing sleeve center of the magnetic field of the magnet roller at a portion where the toner regulating blade and the toner carrier are in contact with each other. Magnetic flux density) is 50 mT or more and 100 mT or less, and the magnetic toner has a magnetic permeability of 0.6 μH / m or more and 1.2 μH / m or less. [Selection figure] None |
