ABSTRACT:
A developer, process cartridge and electrophotographic apparatus that includes the process cartridge and developer, which has as component parts, a main toner body, and an additive that enhances the fluidity of the main toner body. A mixing ratio of the additive to the main toner body, ensures that a contact charger, will not become contaminated, with excess additive that bypasses a cleaning device. While the additive ensures a proper fluidity of the main body of the toner, an excessive amount of additive, beyond a predetermined range, is avoided, so as to prevent the additive from contaminating the contact charger, thus enhancing the lifespan of the contact charger while maintaining image quality.
