PURPOSE:To stabilize the electrification property in various environments and obtain a high-quality image by containing a color toner and a carrier having a specific additional component in coat resin. CONSTITUTION:An insulating nonmagnetic color toner and a carrier with the average grain size 10-200mum coated with electrically insulating resin 0.1-5.0wt.% against the carrier core material weight are contained. A nitrogen-containing compound 0.3-15wt.% is contained against the whole coating resin, this organic resin containing at least fluoroalkyl acrylic polymer is coated on the carrier core material to obtain a carrier. A general compound such as a compound with an amine structure or a compound with a pyridine ring structure can be used for the nitrogen-containing compound, and the compound with an amine structure is preferable in particular. The friction electrification characteristic is stable, and carrier sticking can be excellently prevented. |
