ABSTRACT:
A developer cartridge is configured to be detachably mounted in a main body of an image forming apparatus. A drive member is configured to be driven by the driving force and to move in a moving direction when the developer cartridge is mounted in the apparatus main body. A moving portion is provided on the drive member and is configured to move together with the drive member in the moving direction. An interfering portion is disposed downstream of a predetermined detection position with respect to the moving direction, thereby interfering with the moving portion and preventing the moving portion from passing the predetermined detection position a second time. A detecting portion detects passage of the moving portion at the predetermined detection position. An information determining portion determines information on the developer cartridge based on detection results of the detecting portion.
