To suitably arrange a storge member when a toner cartridge comprises the storage member.SOLUTION: A cartridge unit has: a first unit that has a first support part and a second support part; and a second unit that has a first part to be supported and a second part to be supported and a storage member that stores information and supplies developer to the first unit, the second unit in which the storage member has memory contacts and contact arrangement surfaces on which the memory contacts are arranged. The second unit is configured, in a state where the first part to be supported is supported by the first support part and the second part to be supported is supported by the second support part, to rotate from a first position to a second position to be positioned with respect to the first unit. The second unit rotates from the first position to the second position so that the first part to be supported and the second part to be supported become the center of rotation of the second unit. A normal direction of the contact arrangement surfaces directed in a direction in which the memory contacts are exposed is directed in a direction opposite to the direction in which the second unit rotates from the first position toward the second position.SELECTED DRAWING: Figure 25 【課題】トナーカートリッジが記憶部材を備える場合に、記憶部材を好適に配置する。【解決手段】カートリッジユニットは、第１支持部と第２支持部を有する第１ユニットと、第１被支持部と第２被支持部と、情報を記憶する記憶部材を有し、第１ユニットに現像剤を供給する第２ユニットであって、記憶部材が、メモリ接点とメモリ接点が配置される接点配置面を有する第２ユニットと、を有し、第２ユニットは、第１被支持部が第１支持部に支持され、第２被支持部が第２支持部に支持された状態で、第１位置から第２位置に回転して、第１ユニットに対して位置決めされるように構成され、第１被支持部と第２被支持部が第２ユニットの回転中心となるように、第２ユニットが第１位置から第２位置に回転し、メモリ接点が露出される方向に向いた接点配置面の法線方向は、第２ユニットが第１位置から第２位置に向かう方向に対して逆方向に向く。【選択図】図２５
