| titleOfInvention | Carrier powder for electrophotographic development and electrophotographic developer |
| abstract | The present invention provides a carrier powder having a novel structure with improved resistance to abrasion, wear and crushing in low specific gravity carrier powder. A plurality of magnetic particles are bound with a thermosetting resin (typically a benzoxazine resin) obtained by reacting a reaction product of phenols and amines with an aldehyde in the presence of a basic catalyst. A carrier powder for electrophotographic development composed of composite particles. As the magnetic particles, iron particles having an oxide layer on the surface, ferrite containing one or more metals other than iron such as Cu, Mn, Mg, Ni, Zn, γ-Fe 2 O 3 , magnetite, and the like can be used. Phenols can be suitably used as phenols, aniline as amines, formaldehyde as aldehydes, and aqueous ammonia as a basic catalyst. The carrier powder has, for example, a number average particle diameter D 50 of 1 to 1000 μm and a true density of 1.5 to 4.0 g / cm 3 . [Selection figure] None |
