Provided is a developer replenishing cartridge having excellent precision which replenish a developer to an image formation apparatus regardless of a using condition even the developer is in a consolidation state. The developer replenishing cartridge includes a developer replenishing container and a developer, and is detachably combined with the developer replenishing device. The developer replenishing container includes a pump unit operated to repeatedly convert the state of the internal pressure of a developer receiving unit being lower than air pressure and the state of the internal pressure being upper than air pressure alternately, and the developer has uniaxial collapse stress of 2.5 kPa or more and 3.5 kPa or less in maximum consolidation stress of 10.0 kPa. |
