Abstract
A coated carrier that peeling and wearing of a coating layer are hard to be generated and a method of manufacturing the coated carrier are provided. The coated carrier includes a core particle including a magnetic body, a first resin layer coating the core particle, a resin particle layer including a resin particle fixed to the first resin layer as a single layer, and a second resin layer. The first resin layer includes a first resin having a first reactive group. The resin particle layer is formed of resin particles including a cross-linking resin having a second reactive group which can undergo a cross-linking reaction with the first reactive group. The second resin layer is provided so as to fill gaps between the resin particles.
Claims5
A coated carrier comprising:
- a core particle including a magnetic body;
- a first resin layer including a first resin having a first reactive group, the first resin layer coating the core particle;
- a resin particle layer fixed to the first resin layer as a single layer, the resin particle layer being formed of resin particles comprising a crosslinking resin having a second reactive group which can undergo a cross-linking reaction with the first reactive group;
- and
- a second resin layer provided so as to fill gaps between the resin particles.
A method of manufacturing a coated carrier comprising:
- a first resin layer forming step of forming a first resin layer including a first resin having a first reactive group, on a surface of a core particle including a magnetic body;
- a resin particle layer forming step of forming a resin particle layer on a surface of the first resin by fixing resin particles comprising a cross-linking resin having a second reactive group which can undergo a cross-linking reaction with the first reactive group, to the first resin layer as a single layer;
- and
- a second resin layer forming step of providing a second resin layer so as to fill gaps between the resin particles.
