| abstract | (57) [Summary] [Structure] A two-component developer containing a toner and a carrier. This toner contains toner particles, and the toner particles contain a fixing resin and a predetermined proportion of magnetic powder, and the fixing resin contains a resin having a low molecular weight substance and a polymer having an anionic polar group, respectively. The acid value of the low molecular weight substance is smaller than that of the high molecular weight substance. The carrier particles have core particles made of a predetermined magnetic material and a coating layer that covers the core particles. The coating layer is made of a resin composition containing a resin having a cationic polar group. [Effect] A two-component developer containing no charge control agent is provided. The toner of the developer of the present invention has excellent chargeability, and the generation of reverse polarity toner is reduced, so that the occurrence of toner charging failure can be further suppressed. The developer of the present invention does not cause toner scattering, has a sufficient transfer efficiency, can stably obtain a copy image having a required density for a long time, and has a sufficient fixability of the transferred image. |
