Magnetic toner, and image forming method |
摘要 |
A magnetic toner is provided having at last a binder resin and a magnetic material and having a weight-average particle diameter of 3 mum to 10 mum. The magnetic material has been surface-treated with a low-softening substance (A), and has a compressibility of 35 or more which can be calculated according to a specific expression. The softening point of the magnetic toner is from 40° C. to 85° C. in measurement by a flow tester. The magnetic toner has a resin component containing 1% to 60% by weight of a tetrahydrofuran-insoluble matter. This magnetic toner is superior in low-temperature fixing performance and has good fixing performance in a broad fixing range.
