Summary:PROBLEM TO BE SOLVED: To continue to form high-quality images continuously for a long period while ensuring sufficient durability and charge providing property of a carrier.SOLUTION: A carrier for electrostatic latent image development includes a plurality of carrier particles 10 each including a binder resin 11 and a plurality of magnetic particles 12 dispersed in the binder resin 11. The magnetic particle 12 includes a surface processing core including a magnetic iron oxide particle and its surface processing layer and a resin layer covering the surface of the surface processing core. The resin layer contains a thermosetting resin. The surface processing layer contains a surface processing agent.SELECTED DRAWING: Figure 1 【課題】十分なキャリアの耐久性及び帯電付与性を確保しつつ、長期にわたって継続的に高画質の画像を形成し続ける。【解決手段】静電潜像現像用キャリアが、結着樹脂１１と、結着樹脂１１中に分散した複数の磁性粒子１２とを備えるキャリア粒子１０を、複数含む。磁性粒子１２は、磁性酸化鉄粒子及びその表面処理層を備える表面処理コアと、表面処理コアの表面を覆う樹脂層とを備える。樹脂層は、熱硬化性樹脂を含有する。表面処理層は、表面処理剤を含有する。【選択図】図１
