PURPOSE: To provide an electrostatic charge image developing carrier which is formed by uniformly coating the surfaces of core materials, has excellent coatability with no exposed parts, features a good adhesion property and hardly peels the coating films, a two-component developer formed by using such carrier and process for producing the same.
CONSTITUTION: This electrostatic charge image developing carrier is formed by coating at least part of the surfaces of the granular carrier core materials with a metal oxide formed by a sol-gel method and this two-component developer contains such carrier and a positive charge type toner. This process for producing the electrostatic charge image developing carrier comprises immersing the granular carrier core materials into a soln. contg. a metal alkoxide, then taking out the core materials and heating the core materials, thereby forming the coating films of the metal oxide on the surfaces of the granular carrier core materials. This process for producing the two-component developer comprises mixing the carrier obtd. by this process and the positive charge type toner.
