    摘要： The present invention uses a crystalline resin as a binding resin and provides a toner insuring excellent storability of a resulting image, a method of manufacturing the toner, an electrostatically charged image developer containing the toner, and an image forming method. In the electrophotographic toner containing toner mother particles comprising at least a binding resin and a colorant, a main component of said binding resin comprises a crystalline resin with a melting point in the range from 50 to 120° C. and an average volume particle size in the range from 3.0 to 7.5 μm, while an average value of the BET specific areas of said toner mother particles is in the range from 0.6 to 3.0 m2/g. The electrophotographic toner manufacturing method comprises the steps of coalescing or associating the binding resin particles with colorant particles, and cooling the aggregated particles at the rate of at least 1° C. per minute or more to a temperature below the crystallizing temperature of the binding resin to generate toner particles.

    摘要： An electrophotographic developer and a process for forming an image are provided in that the fixing can be conducted at a lower temperature than the conventional technique, and that are excellent in the powder storage stability, the anti-blocking property and the image storage stability after fixing without impairing the density, the coloring property and the transparency of the image after fixing, and further have appropriate electric charging property without any problem of fogging or cloud with excellent maintenance property of electric charge. The electrophotographic developer contains a toner for developing an electrostatic image containing a coloring agent and a binder resin containing, as a main component, a crystalline resin having a melting point of about from 60 to 120° C., and a carrier having a resin film containing a nitrogen-containing resin on a surface thereof. The process for forming an image is carried out by using the electrophotographic developer.

    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.
