| titleOfInvention | Ferrite carrier core material and ferrite carrier for electrophotographic developer, methods for manufacturing these, and electrographic developer using the ferrite carrier |
| abstract | It is an object of the present invention to provide a ferrite carrier core material and a ferrite carrier for an electrophotographic developer, which have an excellent charging property, hardly cause carrier scattering due to cracking and chipping of the core material, and have a prolonged life, and methods for manufacturing these, and an electrophotographic developer using the ferrite carrier. For this object, the ferrite carrier core material and a ferrite carrier for an electrophotographic developer, wherein (1) the ferrite composition contains 0.5 to 2.5% by weight of Sr, and the presence amount of Sr—Fe oxides satisfies a specific conditional expression, (2) the distribution in the number of the shape factor SF-2 is in a specific range, (3) the BET specific surface area is 0.15 to 0.30 m 2 /g, (4) the average particle diameter D 50 is 20 to 35 μm, and (5) the magnetization is 50 to 65 Am 2 /kg. |
