Abstract:
1. A carrier for use in a two-component developer for developing an electrostatic latent image, comprising: a particulate magnetic core material; and a cover layer located on a surface of the core material and including a crosslinked material and barium sulfate, the cover layer being formed by applying a coating medium including barium sulfate, a copolymer including a unit (A) having the below-mentioned formula (1) and a unit (B) having the below-mentioned formula (2), and a condensation reaction catalyst to the surface of the core material, and heating the applied medium to a temperature of from 100° C. to 230° C. so that the copolymer is hydrolyzed to produce a material having a silanol group, the material and the condensation reaction catalyst are subjected to a condensation reaction to form the crosslinked material, wherein R
