PROBLEM TO BE SOLVED: To provide a picture forming device which can detect an incomplete fitted state of a cartridge part surely and easily caused by that a locking member is placed at a halfway locking position of a locking part. SOLUTION: This device is provided with an increase displacement member 60 which is displaced while linking with a locking member 45 so that displacement quantity δ between displacement quantity in a regular locking position and displacement quantity in a halfway locking position is increased when a cartridge part is in an incomplete state caused by that a locking member 45 is locked at a halfway locking position in a locking part 30. Further, the device is provided with a detecting switch 65 in which an on/off state is switched by displacement of the increase displacement member 60 and which detects an attached state of a cartridge part, and a display means performing alarm and display when the cartridge part is detected as that it is in an incomplete state. |
