    摘要： The invention provides an electrophotographic toner having a crystalline polyester resin; a non-crystalline polyester resin; a colorant; and a releasing agent. A resin (i), that is included in a toluene-soluble component of the toner and having a molecular weight of 30,000 to 100,000 as measured by gel permeation chromatography relative to polystyrene standards, has an acid value A. A resin (ii), that is included in a toluene-soluble component of the toner and having a molecular weight of 8,000 to 12,000 as measured by gel permeation chromatography relative to polystyrene standards, has an acid value B. A resin (iii), that is included in a toluene-insoluble component of the toner, has an acid value C. The acid values A, B, and C satisfy the inequation of B>A>C. The invention further provides an electrophotographic developer using the toner, a toner cartridge storing the toner, and an image forming method using the developer.

    摘要： An electrostatic charge developer includes a carrier having a core material and a resin coating layer covering the surface of the core material, and a toner having a binder resin that contains a non-crystalline polyester resin and a crystalline polyester resin. The resin coating layer contains a copolymer that contains a nitrogen-containing acrylic ester or nitrogen-containing methacrylic ester and an alicyclic acrylic ester or alicyclic methacrylic ester. The non-crystalline polyester resin contains at least an alkyl succinic acid or an anhydride or lower alkyl ester thereof, or an alkenyl succinic acid or an anhydride or lower alkyl ester thereof. The crystalline polyester resin is an aliphatic polyester resin.
