Developer carrier and process for producing the same |
摘要 |
A process for producing a developer carrier is disclosed, which comprises heating a carrier composition containing a resin, magnetic particles and a compound having a lower critical surface energy than the resin, to produce a carrier particle having a higher surface concentration of the compound having a lower critical surface energy. A developer carrier having an average particle size of at least about 50 mu m and containing a fluorine-containing compound and fine magnetic particles dispersed in a binder resin is also disclosed. The developer carriers according to the invention when used in magnetic brush development provide superior charge generation, extended life and improved image reproduction.
