Zusammenfassung: | To provide an electrostatic image developing carrier which is less likely to generate white spots in an image.SOLUTION: An electrostatic image developing carrier is provided, comprising a magnetic particle and a coating layer. The coating layer contains 20 to 60 pts.mass, inclusive, of inorganic particles with respect to 100 pts.mass of a resin. The magnetic particle have an exposure rate of 0 to 5%, inclusive, on the surface. In cross-sectional observation, no gap exists at a boundary between the magnetic particle and the coating layer, or gaps exist at least in parts of the boundary, where an area ratio of the gaps is 0 to 5%, inclusive.SELECTED DRAWING: None
【課題】画像に白抜けを発生させにくい静電荷像現像用キャリアを提供する。【解決手段】静電荷像現像用キャリアは、磁性粒子と被覆層とを有し、被覆層が樹脂100質量部に対して無機粒子を20質量部以上60質量部以下含有し、表面における磁性粒子の露出率が0%以上5%以下であり、断面観察において磁性粒子と被覆層との境界に間隙がない又は境界の少なくとも一部に間隙があり間隙の面積割合が0%以上5%以下である。【選択図】なし |
