Abstract:
The positively-chargeable black toner includes colored resin particles containing a binder resin, carbon black and, as a charge control resin, a quaternary ammonium salt group-containing copolymer, wherein the quaternary ammonium salt group-containing copolymer is a styrene acrylic polymer containing a quaternary ammonium salt group-containing (meth)acrylate monomer unit; wherein a copolymerization ratio of the quaternary ammonium salt group-containing (meth)acrylate monomer in the quaternary ammonium salt group-containing copolymer, is in a range of from 0.1% by mass to 2.5% by mass. A content of the carbon black is in a range of from 10 parts by mass to 15 parts by mass with respect to 100 parts by mass of the binder resin. A blow-off charge amount of the colored resin particles measured by a specific charge amount measuring method, is in a range of from 5 μC/g to 60 μC/g.

Claim (Index 4):
The positively-chargeable black toner according to  claim 2 , wherein the ferrite carrier used in the charge amount measuring method is a standard carrier EF-80B2 (product name, manufactured by: Powdertech Corporation, Mn\u2014Mg\u2014Sr\u2014Fe-based, spherical, non-resin coated, particle diameter: 80 \u03bcm), and the blow-off powder charge amount measuring device is MODEL TB200 (product name, manufactured by: Toshiba Chemical Corporation).
