The wax has, in its DSC endothermic curve, a maximum endothermic peak at 55° C. to 80° C. within the temperature range from 30° C. to 160° C., the maximum endothermic peak having a half width of from 2° C. to 7° C., and the binder resin is composed chiefly of a polyester resin. The toner has a dynamic elastic modulus from 5×102 to 1×105 dN/m2 at 140° C., and its ratio to a dynamic elastic modulus at 170° C. is from 0.05 to 50, and the toner contains 10 to 20% by weight of THF-insoluble matter A of a binder resin component after 8 hours from the start of extraction and 1 to 10% by weight of THF-insoluble matter B of the binder resin component after 24 hours from the start of extraction, the ratio of A to B, B/A, being from 0.1 to 0.8. Also disclosed is a fixing method making use of this toner.

    摘要： A toner is formed of toner particles each comprising at least a binder resin, a colorant and a wax, and inorganic fine powder. The toner is characterized by (a) containing a sulfur-containing polymer, and (b) showing dielectric loss tangent (tan&dgr;) values at 100 kHz assuming a maximum of 2.5×10−2 to 8×10−2 in a temperature range of 100 to 130° C. Because of the combination of the features (a) and (b), the toner can exhibit a good combination of developing performances and fixing performances.

    摘要： A developer supply kit for supplying a developer to an image forming apparatus includes a container for accommodating a developer; an opening provided in the container to permit discharging of the developer; and a feeding member, provided in the container, for feeding the developer by rotation thereof. The feeding member includes a lift portion for lifting the toner in the container, a guiding portion for guiding the toner lifted by the lift portion downwardly toward the opening, and a falling portion for letting the toner lifted by the lifting portion fall without feeding it toward the opening with rotation of the feeding member. The developer has an adhering strength which is not less than 0.60 g/cm2 and less than 3.00 g/cm2 after a vertical pressure of 128.4 g/cm2 is imparted to a layer of the developer.
