    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.
