(57) [Summary] [PROBLEMS] To have good fixing property and excellent charge stability. Provided are a magnetic toner and an image forming method which can provide a high-definition image with a high image density even when used for a long period of time and are suitable for developing and forming a cleaning image. SOLUTION: The toner has at least a binder resin, a releasing agent, and toner particles having a magnetic powder, and has a weight average particle diameter of 3 to 2. 0 μm, the magnetization intensity in a magnetic field of 79.6 kA / m is 10 to 50 Am 2 / kg, and the average circularity is 0.1 μm. 970 or more, the ratio of the weight average particle size to the number average particle size is 1.40 or less, the release ratio of iron and iron compounds is 0.05% to 3.00%, and the viscosity measured by a flow tester is Is 80 × 10 5 Pa · s. A magnetic toner having a temperature of 120 ° C. and a temperature of 1.0 × 10 4 Pa · s of 100 to 150 ° C. is used for an image forming method of a contact charging system. |
