ABSTRACT:
The present invention provides an electrostatic image developing carrier which exhibits an enhanced maintenance of image quality, can be prevented from being attached to the image and thus can provide an image free of uneven density and background stain and an electrostatic image developer comprising said carrier. A novel electrostatic image developing carrier comprising a ferrite is provided, characterized in that said ferrite has a copper content of from 0.1 ppm to 2,500 ppm, a zinc content of from 0.1 ppm to 5,000 ppm and a nickel content of from 0.1 ppm to 2,000 ppm.
