Ferrite particles, electrophotographic carrier and electrophotographic developer using the same |
| abstract |
When used as a carrier in an electrophotographic image forming apparatus, ferrite particles capable of obtaining a sufficient image density even when the image forming speed is increased are provided. The main component is a material represented by a composition formula M X Fe 3-X O 4 (where M is at least one of Mg and Mn, 0 ≦ X ≦ 1), and at least one of Sr element and Ca element. In a range of 0.1% to 2.5% by weight in total. Here, when used as a carrier, from the viewpoint of obtaining a higher image density, the fluidity after being magnetized under a magnetic field of 1000 / (4π) kA / m (1000 oersted) is 40 seconds or more. Is preferred. The residual magnetization σr is preferably 3 Am 2 / kg or more. [Selection figure] None |
