WIPO Patent Application WO/2014/147845

A1

Disclosed is a developer supply kit that comprises a developer supply container and a developer contained in the developer supply container, and that is attachable/detachable to/from a developer supply device. The developer supply container comprises: a developer containing part that contains the developer; a discharge opening for discharging the developer contained in the developer containing part; a drive receiving part to which a driving force is input from the developer supply device; and a pump part that operates such that the inner pressure of the developer containing part is repeatedly alternated between a state lower than atmospheric pressure and a state higher than atmospheric pressure by the driving force received by the drive receiving part. The developer contained in the developer supply container includes a toner including a binder resin and a coloring agent, and the developer satisfies the following formulae: 10 ≤ E (mJ) ≤ 80, and 0.4 ≤ Ea (mJ) ≤ 2.0; wherein E is the total energy when ventilation is not performed, and Ea is the total energy when ventilation is performed.
