PROBLEM TO BE SOLVED: To provide a system having a cartridge with two units which can be detected at a low cost.SOLUTION: A cartridge can be mounted on/dismounted from an image forming device body, and includes a first unit (developing unit 7) configured to store developer and a second unit having a photoreceptor and configured to allow the first unit to be detachably mounted thereon. The first unit includes a first detected section 115 which comes into contact with detection means (contact arm 91) of the image forming device body and is detected by the detection means when it is displaced irreversibly from a new-product position to a use position in response to an input of a driving force from the image forming device body. The second unit includes a second detected section 215 which comes into contact with the detection means which detects the first detected section 115 and is detected by the detection means when it is displaced irreversibly from the new-product position to the use position in response to an input of a driving force from the image forming device body. |
