Abstract
This invention relates to carriers for electrophotography comprising a binder component including a binder resin, a polymeric-magnetic coordination complex, and an inorganic magnetic material dispersed in the binder component at the ratio of 100-900 parts by weight to 100 parts by weight of the binder component, which effect the electrical resistance as well as magnetic properties. Carriers of the invention are suitable, in particular, for a copier furnished with a high rotation developing sleeve.
