Carrier for developer.

摘要

Disclosed is a carrier for a two-component developer, which comprises specific sintered ferrite particles obtained by modifying ferrite customarily used for a carrier, and which can provide a copied image having a high quality, especially an excellent gradation, while maintaining a high durability of the carrier. This carrier comprises sintered ferrite particles having an internal pore ratio, based on the area, of 3 to 20% in an amount of 50 to 80% by weight based on the entire carrier, and the developing voltage dependency of the electric resistance of the carrier is reduced and controlled to an appropriate level. <IMAGE>
