Title: CARTRIDGE AND IMAGING DEVICE
Abstract:
[Problem] To appropriately manage service life of a cartridge in a cartridge used in an imaging device, and an imaging device. [Solution] This developer cartridge 1 comprises a detection gear 52 having a first protrusion 521, and a cartridge IC 62. The imaging device has a sensor that detects movement of the first protrusion 521. The imaging device writes new product determination information to the cartridge IC 62 if the detection signal from the sensor has a new product waveform. As a consequence, it is possible to determine on the basis of information inside the cartridge IC 62 whether the new production detection of that developer cartridge 1 has already been completed in the imaging device. Therefore, it is possible to verify special situations, such as when new product determination information can be obtained from the first protrusion 521, regardless of whether new product determination information has already been stored in the cartridge IC 62. As a consequence, it is possible to appropriately manage the service life of the developer cartridge 1.
